Answer:

D. 8

E. 130

Step-by-step explanation:

D. set the equations equal to each other than solve and try to get one side with the x's.

10x+50=5x+90

-5x          -5x

5x+50=90

    -50   -50

5x=40

divide 5 on both sides

x=8

E. plug in 8 as x for either equation

=5(8)+90

=40+90

=130

=10(8)+50

=80+50

=130
