Question

solve the following simultaneous equation graphically
3x -y = 2 ,2x + y = 8​

Answer 1

Answer:

3x-y=2

hence x=2+y/3

X. 2. 3. 4

y. 0. 3. 6

EQ 2

2x+y=8

hence

y=8-2x

X. 0 1. 2

y. 8. 6. 4

now plot these pints

Answer 2

Answer:

3x-y=2.

we can write- =3(1)-(1)=2

= 3-1=2

2x + y = 8

we can write 2(3) + 2 = 8

6 + 2 = 8
