how did you solve for the equations to get x and y?
if you re arrange the equation you get 1.5x=622-4y, how do you get x from here? do you simply substitute the variable with 223?

Hello Dalai,
 
Multiply the first equation by 4 giving you ----
4x+4y= 892
1.5x+4y=622
Subtract the two equations
 
2.5x=270
x=270/2.5=108
Substitute back to get y 
 
Hope that helps you
