Question

If 6/x+1=2/y-1 and y=-1/2 find x

Answer 1

6/x+1 = 2/y-1
6/x+1 = 2/(-1/2) -1 (Substitute for y = -1/2)
6/x+1 =(-2*2)-1 (Taking 2 to numerator)
6/x+1 = -4-1
6/x+1 = -5
6/x = -5-1
6/x = -6
-6x = 6 (Cross multiplication)
x= 6/-6
Therefore, x = -1

Answer 2

Answer:

6/x+1 = 2/y-1

6/x+1 = 2/(-1/2) -1 (Substitute for y = -1/2)

6/x+1 =(-2*2)-1 (Taking 2 to numerator)

6/x+1 = -4-1

6/x+1 = -5

6/x = -5-1

6/x = -6

-6x = 6 (Cross multiplication)

x= 6/-6

Therefore, x = -18/7
