Answer:

X=16/3=5.33

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.

2+3x=18

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
