Solve each system of equations using the substitution method. Show all your work.

1. Solve the system of equations:

y = x + 3

2x + y = 9

2. Solve the system of equations:

x = 2y - 1

3x - 4y = 1

3. Solve the system of equations:

y = -2x + 5

4x + 2y = 10

4. Solve the system of equations:

x + y = 7

2x - y = 2

5. When using the substitution method, the first step is to solve one of the equations for one of the .

6. After substituting, you will have a single equation with only one .

7. Once you find the value of the first variable, it back into one of the original equations to find the second variable.

8. The substitution method is only used when both equations are already solved for 'y'.
