Solve for x: 9x + 16 = 6x + 1.

5 answers

9x + 16 = 6x + 1
Subtract 6x from both sides:
3x + 16 = 1
Subtract 16 from both sides:
3x = -15
Divide by 3:
x = -5

Therefore, x = -5.
Solve for x: 4x - 3 = 3x - 9
4x - 3 = 3x - 9
Subtract 3x from both sides:
x - 3 = -9
Add 3 to both sides:
x = -6

Therefore, x = -6.
Solve for x: 3x - 3 = 6x + 18.
3x - 3 = 6x + 18
Subtract 3x from both sides:
-3 = 3x + 18
Subtract 18 from both sides:
-21 = 3x
Divide by 3:
x = -7

Therefore, x = -7.
