Question

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

Answer 1

Answer:

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!

Answer 2

This is step by step for you

6(x+3)=21

6 times X would be 6x

6 time three would be 18

You always wanna do what’s in parentheses first

So now your problem would be 6x+18=21

Now you subtract 18 from 21 to get the 6x by itself and it would look like this now 6x=3

Now divide 6 by itself and by 3 and you would get x=3
