Question

What is the value of the y-coordinate of the solution to the system of equations 2x=y=8 and x-3y=-3

Answer 1

Is that supposed to be 2x-y=8 ?

Answer 2

yes my mistake sorry

Answer 3

2x-y=8 equation I
x-3y=-3 equation II

Multiply equation II by 2

2x-y=8 equation III
2x-6y=-6 equation IV

Subtract equation IV from equation III to get rid of the 2x

-y-(-6y)=8-(-6)
-y+6y=8+6
5y=14
y=15/4

Answer 4

Hope that helps
