Question

Which of the graphs below represent the graphical solution to the following system of equations?

4x + y = 5
3x – 7y = 27

Answer 1

solve the equations simultaniously.

Answer 2

the value u get are the cordinates where the lines meet.

Answer 3

\[4x+y=5=> y=-4x+5\]
\[3x-7y=27=> -7y=-3x+27 => y=\frac{3}{7}x-\frac{27}{7}\]

Answer 4

Answer 5

\[-4x+5=\frac{3}{7}x-\frac{27}{7}\]
solve this for x
then plug into one of the equations to find y
this is where they meet
