solve for x

Question

-7(5x-10)-10=25

Answer 1

To solve the equation \(-7(5x - 10) - 10 = 25\), follow these steps:

1. Distribute \(-7\) to both terms inside the parentheses: \[ -7 \times 5x + (-7) \times (-10) = -35x + 70 \]

   So, the equation becomes: \[ -35x + 70 - 10 = 25 \]

2. Simplify the left side by combining like terms: \[ -35x + 60 = 25 \]

3. Subtract \(60\) from both sides: \[ -35x = 25 - 60 \] \[ -35x = -35 \]

4. Divide both sides by \(-35\): \[ x = 1 \]

Thus, the solution is: \[ \boxed{1} \]
