Question

solve the following simultaneous equation using graphical method 4x=y-5, y=2x+1.​​

Answer 1

Answer:

4x=y−5

x 0 2 −2

y 5 13 −3

y=2x+1

x 0 2 −2

y 1 5 −3

Plotting both the equations on graph, as shown, (x,y)=(−2,−3) is the solution of the given pair of equations.

solution

Answer 2

Solve 4x=y−5;y=2x+1

x=−2 and y=−3
