Answer 3

Let's solve the equations one by one:

1. X • 50 = 600 - 150

First, let's simplify the right side of the equation: 600 - 150 = 450

Now we have: X • 50 = 450

To isolate X, we need to divide both sides of the equation by 50: (X • 50) / 50 = 450 / 50

This simplifies to: X = 9

Therefore, the solution to the equation is X = 9.

2. 1560 - X = 7 • 90

First, let's simplify the right side of the equation: 7 • 90 = 630

Now we have: 1560 - X = 630

To isolate X, we need to subtract 1560 from both sides of the equation: (1560 - X) - 1560 = 630 - 1560

This simplifies to: -X = -930

To solve for X, we multiply both sides of the equation by -1 to change the sign: (-1) • (-X) = (-1) • (-930)

This simplifies to: X = 930

Therefore, the solution to the equation is X = 930.
