Question

Solve for the variable of x

2 7

___=___

x+6 x+16

Answer 1

Just cross multiply and you get 2(x+16)= 7(x+6)

2x +32 = 7x +42

5x= -10

x=-2

Answer 2

You get rid of the denominators with multiplication

Example:

4. 10

___ = ____

×+2. x+18

(X+2)(x+18)(4/x+2)=(x+2)(10/x+18)(x+18)

(X+18)4=10(x+2)

4x+72=10x+20

-4x. -4x

72=6x+20

-20. -20

52=6x

52/6 = x
