Question

if 31x + 43y = 117 and 43x + 31y = 105 then, find the value of x+y
​

Answer 1

Step-by-step explanation:

31x + 43y = 117 — (1)

43x + 31y = 105 — (2)

Adding both (1) and (2),

74(x+y) = 222

x+y = 3

Answer 2

The answer is 1 + 2 that is 3(x = 1, y = 2), it took a long time, so can you please mark it as the brainliest answer?
