x 8
What is the NEXT step in solving this system of equations, and
what is the solution for the value of "y"?
O Go back to one of the original equations (you can choose either one) and
plug in 8 for x; y = 2
Go back to one of the original equations (you have to choose the 2nd
equation) and plug in 8 for x; y = 2
O Go back to one of the original equations (you can choose either one) and
plug in 8 for x; y = -2
O There isn't a NEXT step; The problem is completed solved!

Solve the system. 2x 5y 6 and 3x y 26
We can create opposites by multiplying the entire 2nd equation by 5. This
will give us a 5y and a -5y that will cancel.
Multiply the entire
bottom equation by 5
The new equation now has
terms that are opposites.
2x 5y 6
+5(3x + y = 26)
2x - 5y 6
+ 15x+ 5y = 130

2x 5y 6
+ 15x + 5y = 130
= 136
17x+ Oy =
