Question

Solve the following for y: 9x − 3y = 18 (5 points) y = 3x + 6 y = 3x − 6 y = −3x − 6 y = −3x + 6

Answer 1

y = 3x - 6

Explanation:

given 9x - 3y = 18

isolate - 3y by subtracting 9x from both sides of the equation

- 3y = 18 - 9x ( divide all terms by - 3 )

y =
`(18)/(-3)` -
`(9x)/(-3)`

= - 6 + 3x = 3x - 6
