Question

2x+y=2 and 3x+y=5 solve graphically​

Answer 1

Answer:

2x+y=2

-(3x+y) =-(5)

-x= -3

x=3

then y=5-3x

y=5-9

y= -4

Answer 2

2x + y = 2

3x + y = 5

Ans:-

2x + y - 2 = 0 -------------(1)

3x + y - 5 = 0 -------------(2)

By elimination method:-

1       -2        2         1

1       -5        3         1

=> x/-5-(-2) = y/-6-(-10) = 1/2-3

=> x/-3 = y/4 = 1/-1

=> x/-3 = -1

=> x = 3 (Answer)

=> y/4 = 1/-1

=> y = -4 (Answer)

Hope it helps!
