Given the equation:

x - y = -3

Solve for x, and y.

Solution:

We can solve for x and y separately.

Solve for x.

In order to solve for x, we simply need to transpose -y to the other side of the equation, hence we must take note that in transposing a number, the sign changes.

x - y = -3

x = y -3

Solve for y.

In order to solve for y, we transpose -y and -3 to the opposite sides of the equation.

x - y = -3

y = x + 3

Final answer:

x = y -3

y = x + 3
