​

Answer 1

Hey Mate ✌✌

Here is your answer...

____________________

Answer:

x = 1, y = 2

Step-by-step explanation:

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

4x + 3y - 10 = 0 ...(2)

Multiply 1st equation with 3

3x - 3y + 3 = 0 ....(3)

Add equations (2) and (3)

4x + 3y - 10 + 3x - 3y + 3 = 0

7x - 7 = 0

7x = 7

x = 7/7

x = 1

Then, from equation (1)

x - y + 1 = 0

1 - y + 1 = 0

y = 1 + 1

y = 2

Answer 2

x-y=-1×4

4x+3y=10×1

4x-4y=-4

4x+3y=10

=>-7y=-14

=>y=2

substitute'y' in equation 1.

x-2=-1

=>X=-1+2

=>X=1
