all the examples my teacher gave did not involve a x on the other side

3x-2y=42......EQ 1
5x+4y=4.........EQ 2 
mutiply eq 1 by 2 
now it becomes
6x -4y =84
5x+4y=4
now eliminate 4y , it would be cancel 
6x=84
5x=4
adding them 
11x=88
x=88\11
x=8
now put the value of x in eq 2 
5(2)+4y=4
4y=4-10
4y=-6
y=-6\4
y=-3\2
so the solution set is { ( 8,-3\2) }
this is the correct answer
