Given:
4x - 5y = 15
Solution:
We can solve the given values of x and y separately.
Solve for x.
Transpose -5y on the other side of the equation, hence we must take note that in transposing a number, the sign changes.
4x -5y = 15
4x = 15 + 5y
Divide both sides by 4 in order to get the value of x.
x = 15/4 + 5/4y
Solve for y.
4x -5y = 15
5y = 4x - 15
y = 4/5x - 3
Final answer:
x = 15/4 + 5/4y
y = 4/5x - 3
