Solve x for the first equation and then solve the second equation.
7=6x-11 ---> add 11 to each side
7+11=6x-11+11
18=6x ---> divide by 6
3=x
-2x-3y=-7 ---> substitute 3 for x
-2(3)-3y=-7 ---> multiply -2 and 3
-6-3y=-7 ---> add 6 to each side
-6-3y+6=-7+6
-3y=-1 ---> divide by -3
y=[tex] \frac{1}{3} [/tex]
