Dominick Gentry · Answer 1

4x - 4y = 10

1. Factor out the common term 4

4 (x - y) = 10

2. Divide both sides by 4

x - y = 10/4

3. Simplify 10/4 to 5/2

x - y = 5/2

4. Add y to both sides

x = 5/2 + y

3x + 2y = 5

1. Subtract 2y from both sides

3x = 5 - 2y

2. Divide both sides by 3

x = 5 - 2y/3
