x+2y =11
-x+5y=17
Just add these equations together, and the x terms subtract out. Now you can solve for y:
7y=28
y=4
Now substitute this value of y=4 back into either equation. The first equation will do:
x+2y=11
x+2(4)=11
x+8=11
x=3
Check by substituting both numbers into the second equation:
-x+5y=17
-3+5(4)=17
-3+20=17
IT CHECKS!!
