Answer:

x = -61

Step-by-step explanation:

[tex]\frac{6}{x+7}=\frac{7}{x-2}[/tex]

First we state that the solution cannot contain: {-7, 2}, because we would end up with a 0 in the denominator.

Then we can cross multiply:

6(x - 2)=7(x+7)

6x - 12 = 7x + 49

7x + 49 = 6x - 12

x + 61 = 0

x = -61
