Answer 1

Answer:

x=-1 and y=4

Step-by-step explanation:

y=-3x+1

2x+5y=18

Put x and y on the same side for 1st equation

3x+y=1

2x+5y=18

Multiply top by -5

-15x-5y=-5

2x+5y=18

Add both equations onto each other

-13x=13

x=-1

Plug x=1 into any equation used

2(-1)+5y=18

-2+5y=18

5y=20

y=4
