1.4f%2B1.1=8.3-f Start with the given equation.


10%281.4f%2B1.1%29=10%288.3-f%29 Multiply both sides by 10 to clear out the decimals.


14f%2B11=83-10f Distribute and multiply.


14f=83-10f-11 Subtract 11 from both sides.


14f%2B10f=83-11 Add 10f to both sides.


24f=83-11 Combine like terms on the left side.


24f=72 Combine like terms on the right side.


f=%2872%29%2F%2824%29 Divide both sides by 24 to isolate f.


f=3 Reduce.

1.4f+1.1=8.3-f
add f to both sides
2.4f+1.1=8.3
subtract 1.1 from both sides
2.4f+1.1-1.1=8.3-1.1
2.4f=7.2
divide by 2.4
2.4f/2.4=7.2/2.4
f=3
