Just substitute the given values of 'y' in the equation to find 'x'.

1) y = 150

=》y = 250 - 20x

=》150 = 250 - 20x

=》150 - 250 = -20x

=》-100 = -20x

=》-100/-20 = x

=》5 = x

2) y = -1150

=》y = 250 - 20x

=》-1150 = 250 - 20x

=》-1150 - 250 = -20x

=》 -1400 = -2px

=》-1400/-20 = x

=》70 = x

Answer:

1) y=250-20x

150=250-20x

150-250= -20x

-100= -20x

-100/-20= -20x/-20

5= x

x=5

2) y=-1150

-1150=250-20x

-1150-250= -20x

-1400= -20x

-1400/-20= -20x/20

70= x

or x=70
