Question

Find the value of x.

Answer 1

or,6x+6=9x-9

or,6+9= 9x-6x

or,15=3x

or,15/3=X

therefore,X=5ans

Answer 2

x=3

Explanation:

32/24=(6x+6)/(9x-9)

simplify by 8 in the left

4/3=6(x+1)/9(x-1)

simplify by 3 in the right

4/3=2(x+1)/3(x-1)

*3 *3

4=2(x+1)/(x-1)

(x+1)/(x-1)=4/2=2

so x+1=2(x-1)=2x-2

-x -x

1=x-2

+2 +2

3=x

so x=3

verify (6*3+6)/(9*3-9)=32/24

24/18=32/24

simplify by 6 in the left

4/3=32/24

simplify by 8 in the right

4/3=4/3 TRUE
