Question

plz give correct answer​

Answer 1

Answer:

-1

Step-by-step explanation:

4x+3y=24

3x+4y=25

We multipled 3 and 4 respectively in equations

then we get new equations

12x+9y=72

12x+16y=100

now by solve this equation

you will get

-7y=-28

so, y=4

then calculate the value of X by putting the value of y in any equations

4x=24-12

4x=12

x=3

now calculate x-y=(3-4)=-1

Answer 2

Answer:

Step-by-step explanation:

Given,

4x+3y=25  ------(1)

3x+4y=24  ------(2)

Multiply first equation by 3 and second by 4.

12x+9y=75

12x+16y=96

Subtracting first equation from second

7y=21

y=3

put y=3 in eqn (1) we get,

x=4

Now,

x−y=4−3=1Given,

4x+3y=25  ------(1)

3x+4y=24  ------(2)

Multiply first equation by 3 and second by 4.

12x+9y=75

12x+16y=96

Subtracting first equation from second

7y=21

y=3

put y=3 in eqn (1) we get,

x=4

Now,

x−y=4−3=1
