Answer:
x = 9
Explanation:
50 - 3x = 15 + 2x
Subtract 15 to both sides...
50 - 15 - 3x = 2x
Add 3x to both sides...
50 - 15 = 2x + 3x
35 = 5x
5x = 35
x = 7
50 - 3x = 15 + 2x (Given)
50 = 5x + 15 (Add 3x to both sides and add like terms.)
35 = 5x (Subtract 15 on both sides and add like terms.)
7 = x (Divide 5 on both sides and solve.)
