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
