Question

Solve for x 78.2+0.5x=287

Answer 1

x*78.2+0.5=287

x*78.2*10+0.5*10=287*10

782+5=2870

782x+5-5=2865

782x=2865

782x/782=2865/782

2865/782

Answer 2

1. move 78.2 over to the over side. This will give you 287-78.2.

2. when you have .5x = 208.8, divide both sides by .5

3. this should give you x= 417.6

4. make sure to check your work by plugging you answer back into x.
