What is the value of x? 6 + 8x = 5x 2 a) -2 b) -1 c) 1/3 d) 3

The ans is choice D. since there nothing under 5x, imagine there is a 1 under. After that, you can simply cross multiply, so it would be 1(6+8x)= 2(5x). 6+8x= 10x now combine like terms so subtract 8x from both sides and divide 6 by 2 and you will get 3 

I just took the test the answer is D.3
