Math Problem Statement

Solve -3x - 5y = -2 for y

Solution

The equation in the image is:

3x5y=2-3x - 5y = -2

We are solving for yy in terms of xx.

Steps to solve for yy:

  1. Start with the original equation: 3x5y=2-3x - 5y = -2

  2. Add 3x3x to both sides to isolate the yy-term: 5y=3x2-5y = 3x - 2

  3. Divide both sides by 5-5 to solve for yy: y=3x25y = \frac{3x - 2}{-5}

  4. Simplify the expression: y=3x5+25y = -\frac{3x}{5} + \frac{2}{5}

So, the solution for yy is:

y=3x5+25y = -\frac{3x}{5} + \frac{2}{5}
