You can put this solution on YOUR website! Us the substitution method to solve the following system
1/5x+1/5y=9
Divide thru by 1/5 to get:
x + y = 45
--------------
1/3x-1/4y=8
Multiply thru by 12 to get:
4x + 3y = 96
----------------
Solve the 1st for x:
x = 45-y
Substitute into the 2nd to get:
4(45-y) + 3y = 96
180 -4y + 3y = 96
y = 84
-------------
Substitute into x = 45-y to solve for "x":
x = 45 - 84
x = -39
