Question 205513: i need to know how to solve for X in this formula, -4(3-x)=2(x+6)
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! -4(3-x)=2(x+6)
Step 1: Remove parentheses by Distributive Property
-12+4x = 2x + 12
Step 2: Get all the x terms on one side by subtracting 2x from each side
-12 + 4x - 2x = 2x -2x + 12
-12 + 2x = 12
Step 3: Get all number terms on the other side by adding +12 to each side
-12 + 12 + 2x = 12 + 12
2x = 24
Step 4: Divide both sides by 2
x=12
