Answer 3

To solve the equation 4(5 - 3x) = 3 - (2 - 4x) + 7, you'll want to follow these steps:

Step 1: Distribute the 4 on the left side of the equation and the -1 on the right side of the equation to eliminate the parentheses:

4 * 5 - 4 * 3x = 3 - 2 + 4x + 7

This simplifies to:

20 - 12x = 3 - 2 + 4x + 7

Step 2: Combine like terms on both sides of the equation:

-12x + 12x + 2x = 3 - 2 + 7 + 20

This simplifies to:

2x = 28

Step 3: Divide both sides by 2 to isolate x:

2x / 2 = 28 / 2

x = 14

So, the solution to the equation is x = 14.
