Answer:

Solution given:

y=3-4x.....[I]

y=4+½x...[2]

Equating equation 1 and 2

3-4x=4+½x

6-8x=8+x

6-8=8x+x

x=-2/9

x=-0.22

substituting value of x in equation I

y=3-4(-0.22)

y=3.89

(x,y)=(-0.22,3.89)

Yes you are right:
  • y=3-4x
  • y=4+0.5x

Equate and solve

  • 3-4x=4+0.5x
  • -1=4.5x
  • x=-1/4.5
  • x=-0.22

Option B as it only has x=-0.22
