i have to make y the subject of this equation:

4t + 7y - 9 = 0

wod it be y = 4t + 9/7 ??



You need to do the same processes to both sides of the equation.

First, add 9 to both sides.

4t + 7y = 9

Subtract 4t from both sides.

7y = 9 - 4t

Divide both sides by 7.

y = (9-4t)/7

I hope this helps. Thanks for asking.
