Subtract 2 (to isolate the variable and any coefficients)
3x=18-2
3x=16
Divide by 3 (to fully isolate x)
x=16/3
x=5.333 or;
5 and one third

Step-by-step explanation:
Isolate x on one side of the equation.
2+x3=18
2+x*3=18
2+x*3-2=18-2 (First, subtract 2 from both sides.)
18-2 (Solve.)
18-2=16
x*3=16
x*3/3=16/3 (Then, divide by 3 from both sides.)
16/3=5.33
x=16/3=5.33
In conclusion, the final answer is x=16/3=5.33.
