Question

3. Solve the following simultaneous equation by graphically: 2x + y = 5, 3x - y = 5
2
1, 1
=​

Answer 1

Step-by-step explanation:

y=2x+5 __1

3x=5+y

x=5+y/3 __ 2

Cons eq 1

Let x=1 y=7

x=2 y=9

x=0 y=5

Points to plot: (1,7) (2,9) (0,5)

Cons eq 2

Let y=1 x=2

y=4 x=3

y=-2 x=1

Points to plot: (2,1) (3,4) (1,-2)
