Question

An equation and the steps to solve it are shown below:

2x - one over four of (12x + 4) = 3

Step 1: 2x + 3x + 1 = 3
Step 2: 5x + 1 = 3
Step 3: 5x + 1 - 1 = 3 - 1
Step 4: 5x = 2

In which step was the error made and why?

Step 1, because incorrect signs have been used

Step 2, because the terms have been added incorrectly

Step 3, because a number has been subtracted from both sides of the equation

No error was made

Answer 1

look at the original equation and write it out, it should be obvious once you write in numbers

Answer 2

Yea, Make sure you read your math lessons because they show you how to do this.

Answer 3

Well...what did you get?

Answer 4

im still working on it im doing two classes at once

Answer 5

okay just tell me what you get...

Answer 6

Thankyou for being patient

I think c

Answer 9

hopefully

Answer 10

Okay...SHow me were you solved that...

Answer 11

like~show your steps...

Answer 12

I looked at it and your supposed to replace the subtraction with addition i think so i said c

Answer 13

Hold on...

Answer 14

i just looked at step 3

Answer 15

I don't think it's step 3.

Answer 16

\[2x - \frac{ 1 }{ 4 }(12x + 4) = 3\]

here is your equation

Answer 17

Look it over again...

Answer 18

sTEP 1 BECAUSE HE DIDNT DO PERINTHESIS FIRST

Answer 19

Ummm, I guess go for it...I can't tell you the answer! Besides the moderator that got me the first time is viewing this.

Answer 20

ok thankyou for yalls time i appreciate it.

Answer 21

No problem...Bye Compassionate!

Answer 22

You started with this:
\[2x - \frac{ 1 }{ 4 }(12x + 4) = 3\]

In step 1, he got this:
\[2x +3x + 1 = 3\]

The error is in step 1, but it isn't that he "didn't do the parentheses".

Answer 23

oh i got it right then thanks yall.
