Question 173407
The unknown number is x

The equation to solve is

2/3x+1/4x=x+8

The lcd is 12

Therefore multiply each term by 12

8x+3x=12x+96

simplfy terms


11x=12x+96


Subtract 12x from both sides

-x=96 

divide both sides by -1

x=-96


Let's doublecheck our answer

(2(-96)/3} +(-96/4)=-96+8

-64-24=-88
