Question

Rewrite the equation 6x – 9y = 12 in terms of y.A.y = 2x – 4B.y = 3/2x – 2C.y = 2/3x – 4/3D.y + 2/3x = 4/3

Answer 1

We have the equation:

• 6x - 9y = 12

To write it in terms of y, solve for y:

6x - 9y= 12

Subtract 6x from both sides of the equation:

6x - 6x - 9y = 12

-9y = 12 - 6x

Divide both sides by -9

-9y/-9 = (12-6x)/-9

y = -4/3 + 2/3x

Rearrange:

y = 2/3x - 4/3 (option C)
