1) 2x + 17 = 22 + 3xSubtracting 2x from both sides:17 = 22 + xSubtracting 22 from both sides:-5 = xx = -5
3) 25 - 4x = 12 - 5xAdding 5x to both sides:25 + x = 12Subtracting 12 from both sides:x = -13
21 + 45 = 17 + 14xAdding 21 and 45:66 = 17 + 14xSubtracting 17 from both sides:49 = 14xDividing by 14:x = 3.5
1) 2x + 17 = 22 + 3x
Subtracting 2x from both sides:
17 = 22 + x
Subtracting 22 from both sides:
-5 = x
x = -5
3) 25 - 4x = 12 - 5x
Adding 5x to both sides:
25 + x = 12
Subtracting 12 from both sides:
x = -13
21 + 45 = 17 + 14x
Adding 21 and 45:
66 = 17 + 14x
Subtracting 17 from both sides:
49 = 14x
Dividing by 14:
x = 3.5
