Marisol is solving the equation 6(x+3)=21. Find her mistake and correct it.

x = 1/2, See Explanation Below

Explanation:

When you solve the equation, you have to take out the 6 first. The mistake is that you Marisol subtracted from 3 directly instead of factoring the x and the 3 out. Below is what you are supposed to do in order to get the right solution.

Step-by-step for Equation:

6(x+3) = 21

6x + 18 = 21

6x = 21 - 18

6x = 3

x = 3/6

x = 1/2

I hope this helps! If you are kind enough, please give me the brainliest answer. It is greatly appreciated if so. Thank You!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
