Step 1: Distribute the numbers outside the parentheses to each number inside the parentheses
(2 * x) + (2 * 5) = (3 * x) + (-4 * 3)
2x + 10 = 3x - 12
Step 2: Combine like terms
2x goes with 3x. To do this subtract 2x to both sides (subtraction is the opposite of addition)
(2x - 2x) + 10 = (3x - 2x) - 12
0 + 10 = x - 12
10 = x - 12
10 goes with -12. To do this add 12 to both sides (addition is the opposite of subtraction)
10 + 12 = x + (-12 + 12)
22 = x + 0
22 = x
Check:
2(22 + 5) = 3(22 - 4)
2(27) = 3(18)
54 = 54
Hope this helped!
