To solve the equation 3x + 5y = 15 for y, you need to isolate y on one side of the equation.
Starting with the given equation:
3x + 5y = 15
To isolate y, subtract 3x from both sides:
5y = 15 - 3x
Now, divide both sides of the equation by 5 to solve for y:
y = (15 - 3x)/5
Therefore, the expression for y is (15 - 3x)/5.
solve the equaiton 3x + 5y = 15 for y
