Question

Rearrange each of the following formula so the pronumeral in the bracket becomes the subject of the equation

9x+3y-27=0
(Y)

Answer 1

y = 9 - 3x

Explanation:

9x + 3y - 27 = 0 ( add 27 to both sides )

9x + 3y = 27 ( subtract 9x from both sides )

3y = 27 - 9x ( divide through by 3 )

y = 9 - 3x
