4 times a number less than 6 is 8 more than twice that number. find the number.
Serhud [2]
First, let's break the worded equation up into two parts:

- "<span>4 times a number less than 6'

This is 4 * (6-x)

- "</span><span>8 more than twice that number"

This is 2x+8


Now combine these two expressions:

</span>4 * (6-x) =  2x+8

4 * (6-x) = 2 * (x+4) 

2 * (6-x) = x+4

12-2x = x+4

-3x = -8

x = 8/3


If you have any questions, please leave it in the comment section below.

Hope this helps!

Explain why the equation 4x + 5 = 4x - 1 has no solutions.
expeople1 [14]

4x + 5 = 4x - 1


Move all terms containing

x to the left side of the equation.


4x-4x+5=-1


Subtract 4x-4x =0


0+5= 1


5= -1


Since −1≠5, there are no solutions.No solution
