Question

Test the solution x=3 for each equation

Answer 1

[see below]

Explanation:

`3x^2-4x+7=11\\\\3(3)^2-4(3)+7=11\\\\3*3^2-12+7=11\\\\3^3-12+7=11\\\\27-12+7=11\\\\27-5=11\\\\\boxed{22\\eq 11}`

3 would not be a solution to the equation.

Hope this helps!

Answer 2

Answer: this is not equivalent 81-12+7=11

Step-by-step explanation: this is not equal because 81-12 is 69 and 69+7 will give you 76 witch is not equal to 11
