Solve the equation 8x - 7x + 130 = 260. What is x?

Explanation:
Combining like terms on the left simplifies the equation: 8x - 7x becomes x, so you have x + 130 = 260. To isolate x, subtract 130 from both sides, giving x = 130. Checking by substitution confirms it works: 8(130) - 7(130) + 130 = 1040 - 910 + 130 = 130 + 130 = 260. So the value of x is 130.
