Who can solve this?

7x - (2x - 5) = 12x - 3 - 3x

7x - (2x - 5) = 12x - 3 - 3x

7x - 2x + 5 = 12x - 3 - 3x

5x + 5 = 9x - 3

9x - 5x = 5 + 3

4x = 8

x = 2

X=2 because

Step 1: Simplify both sides of the equation. 7x - (2x - 5) = 12x - 3 - 3x 7x + - 1 (2x - 5) = 12x - 3 - 3x (Distribute the Negative Sign) 7x + - 1 (2x) + (-1) (-5) = 12x - 3 - 3x 7x + - 2x + 5 = 12x - 3 - 3x 7x + - 2x + 5 = 12x + - 3 + - 3x (7x + - 2x) + (5) = (12x + - 3x) + (-3) (Combine Like Terms) 5x + 5 = 9x + - 3 5x + 5 = 9x - 3 Step 2: Subtract 9x from both sides. 5x + 5 - 9x = 9x - 3 - 9x - 4x + 5 = - 3 Step 3: Subtract 5 from both sides. - 4x + 5 - 5 = - 3 - 5 - 4x = - 8 Step 4: Divide both sides by - 4. - 4x / - 4 = - 8 / - 4 x = 2
