Respuesta :
Simplify both sides of the equation.
3(−3x+9)=−18
(3)(−3x)+(3)(9)=−18(Distribute)
−9x+27=−18
Subtract 27 from both sides.
−9x+27−27=−18−27
−9x=−45
Divide both sides by -9.
−9x/−9=−45/−9
x=5

What is a linear equation?
A linear equation represents an equation that has one or multiple variables with the highest power of the variable is 1.
The given equation is:
3[- 3x + 9] = - 18
⇒ 3 × 3(- x + 3) = - 18
⇒ 9(- x + 3) = - 18
⇒ (- x + 3) = - 2
⇒ x - 3 = 2
⇒ x = 5
