Answer 2

To solve the equation, you need to isolate the variable x. Let's go through the steps to solve the equation:

Given equation: -5(7 - x) - 4(x - 8) = 3

Step 1: Distribute the constants (-5 and -4) across the parentheses: -5 * 7 + 5 * x - 4 * x + 4 * 8 = 3

Simplify the terms: -35 + x - 4x + 32 = 3

Step 2: Combine like terms: -35 - 3x + 32 = 3

-3x - 3 = 3

Step 3: Add 3 to both sides of the equation to isolate the term with x: -3x = 6

Step 4: Divide both sides by -3 to solve for x: x = -6/3 x = -2

So, the solution for the equation is x = -2.
