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
