Answer 2

Solving the Equations

To solve the given equations, we can follow these steps:

1. Solve for x in the first equation: - 5x + 7 = 19 - Subtract 7 from both sides: 5x = 12 - Divide both sides by 5: x = 12/5

2. Solve for y in the second equation: - 9y + 21 = 21 - Subtract 21 from both sides: 9y = 0 - Divide both sides by 9: y = 0

Solution

So, the solutions to the given equations are: - x = 12/5 - y = 0
