You can put this solution on YOUR website!
11 x + 4 y = 102 .............1
Total value
5 x + 4 y = 42 .............2
Eliminate y
multiply (1)by -1
Multiply (2) by 1
-11 x -4 y = -102
5 x + 4 y = 42
Add the two equations
-6 x = -60
/ -6
x = 10
plug value of x in (1)
11 x + 4 y = 102
110 + 4 y = 102
4 y = 102 -110
4 y = -8
y = -2
