Math Problem Statement

9y−3x= 18

Solution

To solve for yy in the equation 9y3x=189y - 3x = 18, follow these steps:

Step 1: Isolate the yy-term.

Add 3x3x to both sides of the equation to get: 9y=3x+189y = 3x + 18

Step 2: Solve for yy.

Now divide everything by 9 to isolate yy: y=3x+189y = \frac{3x + 18}{9} Simplify: y=3x9+189y = \frac{3x}{9} + \frac{18}{9} y=x3+2y = \frac{x}{3} + 2

So, the solution is: y=x3+2y = \frac{x}{3} + 2
