Complete each ordered pair so that it is a solution of the g

Complete each ordered pair so that it is a solution of the given linear equation. y equals one fifth x minus 7y= 1 5x7; left parenthesis 20 comma right parenthesis comma left parenthesis comma negative 7 right parenthesis(20, ), ( ,7) The first ordered pair is left parenthesis 20 comma nothing right parenthesis .

Solution

We have been given a linear equation y = x/5 -7.

When x = 20, on substituting this value of x in the given equatoion, we have we have y = 20/5 - 7 = 4 - 7 = - 3 . Thus, the required ordered pair is ( 20, -3).

When y = -7, on substituting this value of y in the given equatoion, we have we have - 7 = x/5 - 7 or, x/5 = - 7 + 7 = 0 so that x = 0. Thus, the required ordered pair is ( 0,-7).
