Answer: x=3

Step-by-step explanation: First we do distributive property in the parentheses. Next we subtract both sides by 6. Lastly we divide both sides by 3. Algebraic Rules!!!

Work:

3(x+2)=15

3x+6=15

3x+6-6=15-6

3x=9

3x/3=9/3

x=3

Multiply the bracket by 3

3x+6=15

3x+6-6=15-6

3x=9

divide by 3 for 3x and 9

3x/3=9/3

x=3

Check answer by using substitution method

3(x+2)=15

3(3+2)= 15

Multiply the bracket by 3

9+6= 15

15= 15

Answer is x= 3
