Answer 2

A) To solve the equation 26(x - 20) = 18(x - 40), we can follow these steps:

1. Distribute the 26 and 18 to the terms inside the parentheses: 26x - 520 = 18x - 720

2. Combine like terms on both sides of the equation: 26x - 18x = -720 + 520 8x = -200

3. Divide both sides of the equation by 8 to isolate x: x = -200/8 x = -25

Therefore, the solution to the equation 26(x - 20) = 18(x - 40) is x = -25.

B) To solve the equation 2x + 4 = 8, we can follow these steps:

1. Subtract 4 from both sides of the equation to isolate the term with x: 2x + 4 - 4 = 8 - 4 2x = 4

2. Divide both sides of the equation by 2 to solve for x: x = 4/2 x = 2

Therefore, the solution to the equation 2x + 4 = 8 is x = 2.
