x/3+y/4=11,
5x/6−y/3=−7
Simplify the both equations:

=−7⇒5x−2y=−42
We have,
4x+3y=132...(1)
5x−2y=−42...(2)
Let us use elimination method to solve the given system of equation.
Multiply (1) by 2 and (2) by 3. And add both the equations.

From (1):4(6)+3y=132
y=108/3=36
Answer x=6 and y=36Solve the following system of equations: 3 + 4 = 11 and 5 + 3 =− 7
