Question 24087
3x-y=11
x+2y=-36


Because both equations are in standard form, it will be easiest to use the elimination method.  To eliminate the y terms, multiply the first equation by 2


2(3x-y)=2*11
x+2y=-36


6x-2y=22
x+2y=-36


7x = -14
x=-2


Substitute the value of x=-2 into the either equation:

3x-y=11
3(-2) - y = 11
-6 -y = 11
-y = 17
y=-17


Check in the second equation:

x+2y=-36
-2 + 2(-17) = -36
-2 - 34 = -36
It checks!!


Solution is the point (-2, -17)
