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.
To make y the subject of the equation 4t + 7y - 9 = 0, you need to isolate y on one side of the equation.
1. Start by adding 9 to both sides of the equation to eliminate the constant term on the left side:
4t + 7y = 9
2. Next, subtract 4t from both sides to eliminate the 4t term on the left side:
7y = 9 - 4t
3. Finally, divide both sides of the equation by 7 to solve for y:
y = (9 - 4t) / 7
So, the correct answer is: y = (9 - 4t) / 7
The expression you provided, y = 4t + 9/7, is incorrect.
