Question

Rearrange the equation so q is the independent variable 9q - 4 = 3r - 6

Answer 1

q =
`(3)/(9)`r -
`(2)/(9)`

Explanation:

9q - 4 = 3r - 6

+4 on both sides

9q = 3r - 2

Divide both sides by 9

q =
`(3)/(9)`r -
`(2)/(9)`

Answer 2

3r = 9q - 4 + 6

r = (9q + 2)/3

Answer: r = (9q + 2)/3
