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!! :)
