Question

How do you solve the rational equation `-8/(5x)+2/(3x)=7/15`?

Answer 1

multiply BOTH sides of the equation by the lowest common denominator for all 3 fractions. The LCD is 15x

after multiplying both sides by 15x, you will obtain:
`-8(3)+2(5)=7x`

or
`-24+10=7x`
which is a nice simple linear equation with NO fractions!

solve by eliminating the fractions first
