First, substitute the values of the variables into the equation:

2x+(3)(6)=36

Then, you must simplify,

2x+18=36

Then, you must factor out 18 to leave x and its coefficient alone on one side of the equation:

2x+18-18=36-18

Then you must simplify the equation and divide by 2 on both sides of the equation to factor out the coefficient:

2x/2=18/2

Then you will simplify and you will find the value of x:

x=9
