`x + 2x + 12x = 81`

Combine like terms.

`15x = 81`

Divide both sides by 15.

`(15x)/15 = 81/15`

` ` `x = 81/15`

Reduce your answer by factor of 3.

`x = 27/5` or `x = 5.4` `lArr`** The solution**

Isolate the variable

x+2x+12x=81

Since all the variables are on one side simply add them up

15x=81

Divide by 15

x=5.4

x + 2x + 12x = 81

First combine the like terms ( 2x and 12x and x )

By combining the like terms , your equation should look like

**15x = 81 **now divide both sides by 15 to get " x " alone

By dividing both sides by 15 , your equation should be

**x = 81/15 **simplify it to

**x = 27/5 **which is your answer

`x+2x+12x=81 `

First of all you have to combine like terms

x+2x+12x=81.

15x=81

Divide by 15 to isolate x.

15x=81/15 = x=5.4
