8(x+2)=5x+16+3x
First, distribute the 8 on the left side:
8x + 16 = 5x + 16 + 3x
Combine like terms:
8x + 16 = 8x + 16
Subtract 8x from both sides:
16 = 16
This equation has infinitely many solutions.
6x+2−4x=2(x+2)
First, distribute the 2 on the right side:
6x + 2 - 4x = 2x + 4
Combine like terms:
2x + 2 = 2x + 4
Subtract 2x from both sides:
2 = 4
This equation has no solution.
3(x+3)=7+3x+6−x
First, distribute the 3 on the left side:
3x + 9 = 7 + 3x + 6 - x
Combine like terms:
3x + 9 = 9 + 2x
Subtract 2x from both sides:
x + 9 = 9
Subtract 9 from both sides:
x = 0
This equation has one solution: x = 0.
