Answer 2

Hey Guy! Here Is Your Answer.

x = –3, y = 5.

Given :

Equation (i) 5x–7y = –50

Equation (ii) 5x+7y= 20

To Find :

Value Of x.

Relation Between (i) and (ii).

10x= –30

x= –30/10

x= –3

Putting The Value Of x in Equation (i).

(5×–3) – 7y = –50

–15 –7y = –50

–7y = –50 + 15

y = –35/–7

Hence, y = 5.
