This is a linear equation with one variable.  To solve such an equation, we separate the variables on one side and the constants on the other side of the equation and then solve for the variable. This can be done as follows:

 

The given equation 14+6a-8=18 can be rewritten as follows

 

6a= 18-14+8

 

6a  =12

 

a= 12/6

    =2
