Given:
1x-7y>7
Determine the ordered pair of the solution set.
Solution:
Ordered pair means we have to solve for the value of x and y individually.
x
Transpose -7y on the other side of the equation, note that when transposing a number, the sign changes.
x > 7y + 7
y
Transpose 1x on the other side of the equation, and divide both sides by -7 in order to get the value of y. In dividing a negative number which is involve in inequalities, we change the inequality sign.
-7y>7 - x
-7y/-7>(7 - x)/-7
y < -1 + 1/7x
Final answer:
x > 7y + 7
y < -1 + 1/7x
