Question

Lizzie solve you equation 2+3x+3=3(x+3)+2x rand got an answer of x=2. Without solving the equation, determine whether or not Lizzy's answer is correct. Show all work and provide reasoning for your answer.

Answer 1

Lizzie's answer is not right as two sides are not equal.

Step-by-step explanation:

Given equation is;

2+3x+3=3(x+3)+2x

Lizzy got;

x=2

We will put this value of x in Equation to determine if the sides are equal or not.

$2+3(2)+3=3(2+3)+2(2)\\2+6+3=3(5)+4\\11=15+4\\11\neq 15$

Lizzie's answer is not right as two sides are not equal.
