Question

5) Solve graphically :- x + y = 5 and 3x - y = 3​

Answer 1

X+Y=5.

x=0, y=5

X=1, y=4

X=2, y=3

3x-y=3

X=0, y=(-3)

X=1, y=0

X=2 , y=3

Step-by-step explanation:

X+y=5

0+y=5

Y=5-0

Y=5

X+y=5

1+y=5

Y=5-1

Y=4

X+y=5

2+y=5

Y=5-2

Y=3

3x-y=3

3(0)-y=3

0-y=3

-y=3-0

Y=(-3)

3x-y=3

3(1)-y=3

3-y=3

-y=3-3

Y=0

3x-y=3

3(2)-y=3

6-y=3

-y=3-6

-Y=-3

Y=3

I hope you understood

Answer 2

Answer:

y = 3

x =2

Explanation :

x+y =5

3x - y =3

y =5 - x

3x - (5 -x) =3

y =5-x

3x-5+x=3

y =5-x

4x =8

y=3

x=2
