Answer:
Option 1. x = 12
Step-by-step explanation:
Given the expression 3(x - 6) = 18
We need to get the value of "x" for the equation to be true
Expand the bracket using the distributive property
3(x-6)=18
3x - 3(6) = 18
3x - 18 = 18
Add 18 to both sides
3x - 18 + 18 = 18 + 18
3x = 36
Divide both sides of the equation by 3:
3x/3 = 36/3
x = 12
Hence the value of x that makes the equation true is 12
