Question

What is the value of x in the following equation?
682.84 - 107.48 = x / 50 - 125.72

The correct answer is

35054

682.84 - 107.48 = 575.36.
Now the equation becomes: 575.36 = x / 50 - 125.72
Adding 125.72 to both sides: 575.36 + 125.72 = x / 50
701.08 = x / 50.
Multiply both sides by 50: x = 701.08 × 50 = 35054.
