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

`(-9x)/(-9)=(7)/(-9)\rightarrow x=(7)/(-9)`

Therefore, the right answer is -7/9.
