Solve the simultaneous equations
x+y=3
y=3x−17

x=5 , y=-2

Step-by-step explanation:

rearrange y=3x-17 to -3x+y=-17

then subtract to get x or y

     x+y=3

- (-3x+y=-17)

       4x=20

         x=20/4

         x=5

then sub in the x value into one of the equations

for x+y=3

    (5)+y=3

          y=3-5

          y= -2

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
