Question

Without actually solving for x and y. Find the value of x + y and x – y
(Linear Equations, Class 10th CBSE)

• 37x + 43y = 123

• 43x + 37y = 117

WRONG ANSWERS WILL BE REPORTED..!!​

Answer 1

Answer:

1.

37x+43y=123...............(1)

43x+37y=117...............(2)

Adding (1) and (2)

80x+80y=240

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

subtracting (2) from (1)

-6x+6y=6

-x+y=1..............(4)

Adding (3) and (4),

2y=4

y=2

(3)==> x=1

solution is x=1 and y=2

Step-by-step explanation:

Its a correct answer
