Question

10. If x=a,y=b is the solutions x - y = 2
ana x+y = 4 then the values of a b are
respectively​

Answer 1

Answer:

a = 3, b = 1

Step-by-step explanation:

a - b = 2----------------1

a + b = 4----------------2       on Subtraction, b and -b get cancelled

2a = 6

a = 3

a = 3 substitute in equation 1

3 - b = 2

- b = 2 - 3

- b = -1

Therefore b = 1

Answer 2

Answer:

$x - y = 2 \\ a - b = 2 \\ a = b + 2$

and

$x + y = 4 \\ a + b = 4$

putting value of a in this equation.

$b + 2 + b = 4 \\ 2b = 2 \\ b = 1$

and

$a = b + 2 \\ a = 1 + 2 \\ a = 3$

Hope it helps you.
