Question

Use the properties of equality to solve the equation 3x +2 - x = 11x + 9. Check your solution.

Answer 1

The given expression is-

$3x+2-x=11x+9$

First, we place all terms with variables on the left, and all terms without variables on the right

$3x-11x-x=9-2\rightarrow-9x=7$

Then, we divide the equation by -9

$\frac{-9x}{-9}=\frac{7}{-9}\rightarrow x=\frac{7}{-9}$

Therefore, the right answer is -7/9.
