Answer 3

To solve the equation 4(5x - 2) = 2x + 10, we will follow the steps below:

1. Distribute the 4 to both terms inside the parentheses: 20x - 8 = 2x + 10

2. Simplify the equation by combining like terms. Subtract 2x from both sides: 20x - 2x - 8 = 2x - 2x + 10 18x - 8 = 10

3. To isolate the variable x, we will add 8 to both sides: 18x - 8 + 8 = 10 + 8 18x = 18

4. Finally, divide both sides by 18 to solve for x: (18x) / 18 = 18 / 18 x = 1

Therefore, the solution to the equation 4(5x - 2) = 2x + 10 is x = 1.
