8/x=4/x+10

What's this proportion

2 ways:

1. solve for x

2. simplify the 10 so it can add to the 4/x

if you use 1. solve for x

8/x=4/x+10

subtract 4/x from both sides

4/x=10

multiply both sides by x

4=10x

divide both side sby 10

0.4=x

proportion is 8/0.4=4/0.4+10

if you use 2. make 10 addable to 4/x

4/x+10/1

multiply 10/1 by x/x

4/x+10x/x = (4+10x) / x

8/x = (4+10x) / x

multiply both sides by x to clear fraciton

8=4+10x

subtract 4

4=10x

divide 10

0.4=x
