Answer:

3)x=0 y=1

Step-by-step explanation:

3) y=3x+1

   

    3x+y=1

    y=1-3x

1-3x=3x+1

1-1=3x+3x

0=6x

x=0

by substitute in 1

     y=3x+1

     y=3*0+1

     y=1

   5)  -5x+1=2x+4

         -5x-2x=4-1

         -7x=3

          x=-3/7

  by substitute in (y=2x+4)

            y=2*-3/7+4

              =25/7
