Question

If (x+5):(x+7)=(x-1):(x+2) find the value of x​

Answer 1

Step-by-step explanation:

Subtract both sides by 1

(x+5)/(x+7)-1=(x-1)/(x+2)-1

(x+5)-(x+7)/x+7=(x-1)-(x+2)/x+2

-2/x+7=-1/x+2

2/x+7=1/x+2

2(x+2)=x+7

2x+4=x+7

x=3

Answer 2

Answer:

x+5/x+7 = x-1/x+2

(x+5)(x+2) = (x-1)(x+7)

x^2 +2x + 5x+10 = x^2 +7x -x -7

7x +10 = 6x -7

x = -17

therefore the value of x is -17
