Answer 3

1) 138 - x = 130 To solve for x, we need to isolate x on one side of the equation. First, we can subtract 138 from both sides: 138 - 138 - x = 130 - 138 -x = -8 Now, we can multiply both sides by -1 to solve for x: x = 8

2) 125 / (x + 5) = 25 To solve for x, we can first multiply both sides by (x + 5): 125 = 25(x + 5) Now, we can distribute 25: 125 = 25x + 125 Subtract 125 from both sides: 0 = 25x Divide both sides by 25: 0 = x So, x = 0

3) 3x + 75 * 4 = 600 First, we can simplify the left side of the equation: 3x + 300 = 600 Subtract 300 from both sides: 3x = 300 Now, divide both sides by 3: x = 100

So, the solutions for the given equations are: 1) x = 8 2) x = 0 3) x = 100
