Use the process of elimation and elimate the x varible. This gives you the y variable. Then you substitue this answer for the x varible. If you need any help with the process of elimantion, I could asist you more.

However, using substitution,
pick either equation and solve for a variable:
3x+y = 38.0
so,
y = 383x
Now substitute that value into the other equation:
2x+3y=40.50
2x + 3(383x) = 40.5
2x + 114  9x = 40.5
7x = 73.5
x = 10.5
y = 383x = 6.5
