Question

help me to write this out...
the sum of three times a number, and 8, is equal to two times the number

Answer 1

Okay the first part "the sum of three times a number" means the answer to 3 multiplied by a variable, let's call the variable, n. So this is what it would look like: \[3 \times n = \]

Do you understand so far @diplomabound?

Answer 2

yes

Answer 3

Okay cool! Now the next part "and 8" I'm guessing it's supposed to be in the same equation that I wrote above so this is what it would look like:

\[3 \times 8n = \]

And the next part, "is equal to two times a number" means that 2 is multiplied by a variable. Let's call this variable x.

Now the equation looks like this:

\[3 \times 8n = 2 \times n\]

Answer 4

Oh sorry I forgot to add the x to that equation I'll change it:

\[3 \times 8n = 2 \times x\]

Answer 5

this is what I got
3(x+8)=2x

Answer 6

your answer is different.

Answer 7

hi welcome to Openstudy! :)

"sum of three times a number and 8" should be \(\sf 3x + 8\)

then the rest of your answers will be right ^_^

Answer 8

Hi data_LG2
so then it should read 3x+8=2x? That's what I came up with

Answer 9

yes, that would be right :)

Answer 10
