Question

FIB- If, 15x + 17y = 14 and 17x +15y = 50, Then x + y = _________. Give answer plz​

Answer 1

$15x + 17y = 14$

$17x + 15y = 50$

$add \: both \: equations$

$32x + 32y = 64$

$32(x + y) = 64$

$x + y = \frac{64}{32}$

$x + y = 2$

Answer 2

Step-by-step explanation:

15x+17y=14....(1)

17x+15y=50...(2)

adding (1)and (2) we get

32x+32y=64

32(x+y)=32×2

cancelling 32 on both sides

therefore, x+y=2
