Question

How to graph 5a-6b=18

Answer 1

`a = ( - 6)/(5) b + (18)/(5)`

`b = ( - 5)/(6) a + 3`

Explanation:

Let's solve for a .

`5a+6b=18`

Step 1: Add -6b to both sides.

`5a+6b+−6b=18+−6b`

`5a=−6b+18`

Step 2: Divide both sides by 5.

`(5a)/(5) = ( - 6b + 18)/(5)`

`a = ( - 6)/(5) b + (18)/(5)`

Let's solve for b.

`5a+6b=18`

Step 1: Add -5a to both sides.

`5a+6b+−5a=18+−5a`

`6b=−5a+18`

Step 2: Divide both sides by 6.

`(6b)/(6) = ( - 5a + 18)/(6)`

`b = ( - 5)/(6) a + 3`
