To solve for x in the equation 5(2x+2) - 4 = 2x + 6:
First, distribute the 5 on the left side: 10x + 10 - 4 = 2x + 6
Combine like terms: 10x + 6 = 2x + 6
Subtract 2x from both sides: 8x + 6 = 6
Subtract 6 from both sides: 8x = 0
Divide both sides by 8: x = 0
Therefore, the equation has one solution: x = 0.
