Question

Whats 3(x + 2) = 21?
show work please !!​

Answer 1

x = 5

Explanation:

You first have to multiply 3 by x and 2, and you would get 3x and 6. 3(x + 2)=3x +6

Then you have to move the 6 to the other side and it will become negative. 3x= -6 +21

Then you subtract 21-6 to get 15. 3x = 15

Then you are left with 3x = 15.

Divide 3 from both sides and you get x =5.

Answer 2

x=5

Explanation:

`3(x+2)=21`

`3x+6=21`

`3x+6-6=21-6\\\\3x=15\\\\(3x)/(3) = (15)/(3) \\\\x=5`
