Question

Solve : 35x – 37y = 68 ; 35y – 37x + 76 = 0​. please full answer​

Answer 1

Rewriting the given equations, we get

35x−37y=68 ...(i)

−37x+35y=−76⇒37x−35y=76 ...(ii)

On adding (i) and (ii) , we get

72x−72y=144

⇒x−y=2 ....(iii)

On subtracting (i) from (ii) , we get

2x+2y=8

⇒x+y=4 ....(iv)

On adding (iii) and (iv) , we get

2x=6

⇒x=3

By putting x=3 in (iv), we get

3+y=4

⇒y=1

Thank you and have a nice day....
