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.
