Practice Using the Substitution Method

Practice Problems

It's time for you to practice. Here are four problems to make sure you understand this method. If you need help along the way, there are hints and videos.

Solve the system of equations.

$$5x−4y=-10$$

$$y=2x-5$$
$$-4x+11y=15$$

$$x=2y$$
$$10x-9y=24$$

$$y=x-2$$
$$-5x+4y=3$$

$$x=2y-15$$
