Answer:
3(x+2)=12
Explanation:
Ok, so this is simple. First you multiply the three on the outside by the x and 2 on the inside using the distributive property. Then you should get 3x (3 times x) + 6 (3 times 2). now that you have 3x+6=12, you can subtract the 6 from both sides. you should end up with 3x=6. To figure out x you should divide both sides by 3. You should end with x = 2.
3(x+2)=12
3x+6=12
3x=6
x=2
