Sagot :

This question is about a linear equation.

The given equation is

[tex]-2x-12=9x+18[/tex]

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

[tex]-2x-9x=18+12[/tex]

Second, we reduce like terms

[tex]-11x=30[/tex]

Third, we divide by -11

[tex]\frac{-11x}{-11}=\frac{30}{-11}\rightarrow x=-\frac{30}{11}[/tex]

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