Solve each equation <br> 1. 3/4 f + 5 = -5<br> 2.-1/5 b - 2/5 = -2<br> Please show work
anzhelika [568]
Sole for f by simplifying both sides of the equation then isolating the variable so that means f=-40 over 3 for number one

for the second equation you do the same thing you did for number one and the answer will be
                                  b=8
