Question

2x+y=95 & 2x+4y=140​

Answer 1

here's the solution..... :-)

Answer 2

$hi..$

$here \: is \: your \: answer..$

$2x + y = 95 \: \: \: \: \: \: ................(1)$

$2x + 4y = 140 \: \: \: ...............(2)$

Subtracting eqn (2) from (1)

2x + y = 95

2x +4y =140

___________________

-3y = -45

y = 45 / 3

y = 15

Put y = 15 in (1).

2x + y = 95

2x + 15 = 95

2x = 95 - 15

2x = 80

x = 40.

Thus ,

$x = 40 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: y = 15$

$hope \: it \: helped..$
