Question

solve for x and y : x+y-1/x-y+1=7 , y-x+1/x-y+1=35​

Answer 1

Step-by-step explanation:

hey mate, here is ur answer..

x+y-1/x-y+1 =7

x+y-1=7(x+y+1)

x+y-1 =7x+7y+7

6x+6y= -8

3x+3y =-4__________(1)

y-x+1/x-y+1=35

y-x+1 = 35(x-y+1)

y-x+1=35x-35y+35

36x-36y =-34

18x-18y = -17________(2)

Multiply equation (1) by 6

18x+18y=-24________(3)

Add equation (2) & (3)

36y = - 41

y = -41/36

put the value of y in equation (1)

3x+3(-41/36)=-4

3x-41/12 = -4

36x-41=-48

36x = -48+41

36x = -7

x= -7/36

hope it helps..
