4(5х-7)-3=9х-9

Let's solve the equation step by step:

1. Distribute the 4 on the left side of the equation: 4(5x - 7) - 3 = 9x - 9 20x - 28 - 3 = 9x - 9 20x - 31 = 9x - 9

2. Combine like terms: 20x - 31 = 9x - 9

3. Subtract 9x from both sides: 20x - 9x - 31 = -9 11x - 31 = -9

4. Add 31 to both sides: 11x = 22

5. Divide by 11 to solve for x: x = 22 / 11 x = 2

Therefore, the solution to the equation is x = 2.
