Question

Solve -2x-12=9x+18 for x. Round your answer to the nearest tenth.

Answer 1

This question is about a linear equation.

The given equation is

`-2x-12=9x+18`

First, we need to organize the equation. On the right side terms without variables, on the left side with variables.

`-2x-9x=18+12`

Second, we reduce like terms

`-11x=30`

Third, we divide by -11

`(-11x)/(-11)=(30)/(-11)\rightarrow x=-(30)/(11)`

Therefore, the variable is equal to -30/11.
