Substitution Steps

1 1. Find the equation with
a variable by itself

Annotations:

- 2x + 3y= 24 2x + y= 8 * = equation with variable by itself

2 2. Solve for the variable by itself.
(Sometime it is already solved for you.)

Annotations:

- 2x + y= 8 changes to y= 8 - 2x

3 3. Substitute or plug in the equation
that is solved into the one that isn't.

Annotations:

- 2x - 3(8 - 2x)= 24

4 4. Solve this equation and get one
of the answers (y or x).

Annotations:

- 2x - 3(8 - 2x) = 24 ... y = -12

5 5. Plug your answer from step
four into one of your equations
(doesn't matter which one)

Annotations:

- 2(-6) - 3y = 24 Answer: x = -6, y = - 12

6 6. Solve and get last answer (y
or x).
