Equations, that have same roots are called equivalent. In particular, equations that don’t have roots are equivalent. Example 1. Equations {x}+ {2}= {7} x +2 = 7 and {2} {x}+ {1}= {11} 2x +1 = 11 are equivalent, because each of them has unique root 5.
Which equation is equivalent to log3 x+5 2?
Rewrite log3 (x+5) = 2 log 3 (x + 5) = 2 in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b ≠ ≠ 1 1, then logb(x) = y log b (x) = y is equivalent to by = x b y = x. 32 = x+5 3 2 = x + 5
How do you set equations equal to each other?
Following are answers to the practice questions:
- The answer is x= 2, y = 1. The coefficients of the y terms are opposites of one another, so when you add the two equations together, you get 7 …
- The answer is x = 4, y = –3. Multiply the terms in the first equation by 2 and the terms in the second equation by 3. …
- The answer is x = –1, y = 3. The second equation is already solved for y. …
How do you find the equivalent expression?
equivalent expressionshave the same value but are presented in a differentformat using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the”equal” rather than 2 as shown here.
Which expressions are equivalent to?
Two mathematical expressions are equivalent if and only if they result in the same value for all matching values of the variables. Therefore, we can determine if two expressions are equivalent by plugging in many different matching values of the variables to make sure we get the same value out of each expression in every instance.

What is equivalent equation example?
For example, if we take 3x + 12 = 7x – 2 and subtract 3x from both sides and add 2 to both sides, we get 14 = 4x. In doing this, we haven’t changed the solution set, so 3x + 12 = 7x – 2 and 14 = 4x are equivalent equations.

How do you equate an equation?
Suppose we have a pair of simultaneous equations, 2x − y = −2 and x + y = 5. We can solve these equations by taking the sum of the left hand sides and equating it to the sum of the right hand sides as follows: 2x − y + (x + y)=3x = 3. So, x = 1.

What is the system of equations that have the same solution called?
Systems of equations that have the same solution are called equivalent systems. Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself. In contrast, we can be sure that two systems of equations are not equivalent …

What is Camila’s 2nd equation?
Camila’s is equivalent. The 1st equation matches the 2nd equation in the original. And, Camila’s 2nd equation is the original 1st equation multiplied by -8. We are allowed to multiply equations by any value as long as we do the entire equation.
What is the solution point of an equation?
The solution point is the point that satisfies both equations, that is, the x and y that make the two sides equal in both equations. So if you add things that are equal to things that are equal, the result must be equal, so the same solution must satisfy the new equation.
