Math Problem Statement

2x+3y=12;y

Solution

To solve the equation 2x+3y=122x + 3y = 12 for yy, we first isolate yy in terms of xx.

Steps:

  1. Start with the equation: 2x+3y=122x + 3y = 12
  2. Subtract 2x2x from both sides to isolate the 3y3y term: 3y=122x3y = 12 - 2x
  3. Now, divide both sides by 3 to solve for yy: y=122x3y = \frac{12 - 2x}{3}
  4. Simplify the expression: y=42x3y = 4 - \frac{2x}{3}

So, the solution for yy in terms of xx is: y=42x3y = 4 - \frac{2x}{3}
