Solve each system of equations using the method of your choice. Homework Help ✎
y + x = −2
5x − 3y = 22
x = 3
7x − 2y = 24
Read Math Notes box in Lesson 6.3.3 on the Elimination Method.
Try rearranging the first equation and then using the Elimination method.
Rearrange the first equation so that x is first. Multiply the top equation by 3 to eliminate y. Add the two equations to solve for x.
Substitute the x-value into either original equations to find y.
x = 2
y = −4
The first equation is already x = 3.
Use it to solve for y.
Substitute x = 3 into the second equation and solve for y.
