Question

Solve each of these systems using the substitution method. Make sure to check your answers ! 2x + 3y = -4 x − 2y = 5

Answer 1

Use the second equation getting x=2y+5
Now, substitute for x in in the first equation and solve for y.

Answer 2

Are you following?

Answer 3

After substituting, the first equation will look like this:
2(2y+5) + 3y = -4 Go ahead and solve for y, then plug in y value in either equation and solve for x. You're done!
