Question

Solve the following simultaneous equations graphically.

1. 2x + 3y = 12 ; x – y = 1

2. x – 3y = 1 ; 3x – 2y + 4 = 0

3. 5x – 6y + 30 = 0 ; 5x + 4y – 20 = 0

4. 3x – y – 2 = 0 ; 2x + y = 8​

Answer 1

Answer:

1. 2x+3y=12____(1)

x-y=1____(2)

equation 2 me 2 se multiple krne pr

y= 2

equation 2 se

x-2=1

x=3
