Question

How do you solve the equation `(-8b-(-9))/(-10)=17`?

Answer 1

`b=179/8`

Explanation:

To eliminate the fraction, multiply both sides of the equation by - 10

`cancel(-10)xx(-8b+9)/cancel(-10)=(-10xx17)`

`rArr -8b+9=-170`

subtract 9 from both sides.

`-8bcancel(+9)cancel(-9)=-170-9`

`rArr-8b=-179`

To solve for b, divide both sides by - 8

`(cancel(-8) b)/cancel(-8)=(-179)/(-8)`

`rArrb=179/8" is the solution"`
