I'm giving a problem to solve for x and I know how to do most 1 varible equations but I'm a little fuzzy on what to do for this type  

 

\(\frac{(x + 20)}{2} = 3x\) 

 

 

Thanks so much for your help and time you spend teaching me how to understand the conept.

\(\frac{(x+20)}{2}=3x\)

 

To take out that fraction multiply both sides by 2

 

\(\frac{(x+20)}{2}*2=3x*2\)

\(x+20=6x\)

 

Then to cancle out the 20 subtract 20 on both sides

\(x + 20 - 20 = 6x - 20\)

\(x=6x-20\)

 

To combine terms subtract 6x on both sides

\(x-6x=6x-20-6x\)

\(-5x=-20\)

 

Then to single out the x on the left divide both sides by -5

\(\frac{-5x}{-5}=\frac{-20}{-5}\)

 

Simplify

\(x = 4\)

 

Your answer for x would be 4

 

Hope this helps ;P
