Given:
x - 5y = 5
Find the ordered pair.
Solution:
Solve first for y in terms of x, then substitute the value of y in the equation.
x - 5y = 5
5y = x +5
Divide both sides by 5 in order to cancel out 5y.
5y/5 =(x + 5)/5
y = 1/5x + 1
Substitute the value to the equation.
x - 5 (1/5x + 1) = 5
x - x + 1 = 5
= 5 - 1
= 4
Final answer:
= 4
