Question

solve the pair of equations x+3y=6 and 2x-3y=3 graphically
​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

x 3 0 6

y 1 2 0

(x,y) (3,1) (0,2) (6,0)

let x=3

3+3y=6

3y=6-3

3y=3

y=3/3

y=1

y=2

x+6=6

x=6-6

x=0

y=0

x+3(0)=6

x=6+0

x=6

x 3 9 12

y 1 5 7

(x,y) (3,1) (9,5) (12,7)

2x-3y=3

3+3y=2x

3+3(1)=2x

3+3=2x

6=2x

6/2=x

3=x

y=t

3+3(5)=2x

3+15=2x

18=2x

18/2=x

x=9

y=7

3+3(7)=2x

3+21=2x

24=2x

24/2=x

12=x
