I need some help in sovling this problem.

x+3y=9
show me how to solve for y.

subtract x from each side.

Then, divdide both sides by 3

To solve the equation x + 3y = 9 for y, follow these steps:

Step 1: Subtract x from each side of the equation:
x + 3y - x = 9 - x
3y = 9 - x

Step 2: Divide both sides of the equation by 3:
3y/3 = (9 - x)/3
y = (9 - x)/3

So the solution for y in terms of x is y = (9 - x)/3.
