help please .

OpenStudy (anonymous):

\[5\left[ 3x-4 \right]=x+1\]

OpenStudy (anonymous):

i need help solving please .

OpenStudy (anonymous):

can you give me the steps please?

OpenStudy (anonymous):

@iGreen @Night-Watcher

OpenStudy (igreen):

First multiply 5 into the parenthesis.. \(5 \times 3x\) \( 5 \times x + 1\)

OpenStudy (anonymous):

\[5\left| 3x-4 \right|=x+1\]

OpenStudy (anonymous):

my bad , its not parenthesis .

OpenStudy (igreen):

Okay, we can break this into 2 separate equations: \(5(3x - 4) = x + 1\) and \(5 \times -(3x - 4) = x + 1\) Can you solve the first one?

OpenStudy (anonymous):

is it 15x-20=x+1?

OpenStudy (igreen):

Yep.

OpenStudy (igreen):

Keep solving it

OpenStudy (anonymous):

do i subtract 20 to both sides?

OpenStudy (anonymous):

i mean add 20.

OpenStudy (anonymous):

i - x which gave me 14x-20=1 then i + 20 to both sides which left me with 14x=21 . am i correct? @iGreen

OpenStudy (igreen):

Yes..now divide 14 to both sides.

OpenStudy (anonymous):

x=1.71

OpenStudy (igreen):

No..check again.

OpenStudy (anonymous):

1.5

OpenStudy (igreen):

Yes, that's correct

OpenStudy (igreen):

Now you have to solve the other one.. @boricua5

OpenStudy (anonymous):

thanks for your help (:

OpenStudy (igreen):

\(5(-3x + 4) = x + 1\)

OpenStudy (anonymous):

i already have the answer so now im going to solve the other one i posted .
