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

$$x = 4$$

Hope this helps ;P
