Question

X + y = 5
2x + 3y = 12​

Answer 1

Answer:

you question is missing

Step-by-step explanation:

x+y=5

this can be written as

x=5-y------------------1

now by putting this value of x in

2x+3y=12

2(5-y)+3y=12

10-2y+3y=12

10+y=12

y=12-10

y=2

now by putting the value of y in 1st equation

x+y=5

x+2=5

x=5-2

x=3

so,

X=3 AND Y=2

Answer 2

Answer:

x=3

y=2

Step-by-step explanation:

we have ,

x+y=5......[1]

2x+3y=12.....[2]

let us take,,,

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

putting (3) in (2)

we get,,

2x+3(5-x)-12=0

2x+15-3x-12=0

-x+3=0

-x=-3

hence x=3......(4)

so,

putting 4 in..... (1)

x+y=5

3+y=5

y=5-3

y=2

hence x=3

and y=2
