Question 394035
x+2y=6
2x-3y=26

so you want to eliminate the Xs , its a lot easier
to do this, just multiply the whould first equation by -2

-2x - 4y = -12
 2x - 3y = 26

X's cancel, now just add it upp

-7y = 14
y = -7 

then to get X, plug it into the original equation

x + 2(-7) = 6
x - 14 = 6
x = 20

the salution would be (20, -7)
