471.7 is the answer....

3(x+y) - 4x + 3y
x=-1.3
y=78.4

1) Substitute the values of x and y into the equation to solve.

2) 3(-1.3+78.4) - 4(-1.3) + 3(78.4)
Do all multiplication first before addition or subtraction.

3) (-3.9+235.2) + 5.2 + 235.2
Notice the center one becomes addition because there were two negatives.

4) 231.3 + 240.4

5) 471.7 is the answer

Hope this helps!! :)
