3f+2.9=4.4
Please help.

______________________________

 - We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.

Equation at the end of Step 1:

 - We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.

 - 0.5 is equal to as a fraction.
