If x + 8y = 20 and x = -3y, then y =

• x+8y=20 then subtitute x=-3y in the equation

• x+8y=20
  x=-3y
  sub value of x in x+8y=20
  -3y+8y=20
  5y=20

• sub x=-3y in equation then u wioll get the output as y=4

• x+8y=20 then sub x=-3y in x and
  then -3y+8Y=20
  5y = 20
  y=4...

• x+8y=20
  implies, -3y+8y=x
  5y=x
  y=x/5

• y=-10
  put the value of x in that equation and solve it.
