3x1/2(5x+2)=14

OpenStudy (anonymous):

What's X? Thanks

OpenStudy (anonymous):

\[3\cdot \frac{1}{2(5x+2)}=14\]

OpenStudy (anonymous):

Is that what you meant?

OpenStudy (anonymous):

No

OpenStudy (anonymous):

What is wrong?

OpenStudy (anonymous):

\[3\cdot \frac{1}{2}(5x+2)=14\]

OpenStudy (anonymous):

Is that correct?

OpenStudy (anonymous):

Yes, except it's 3 + thanks. :)

OpenStudy (anonymous):

3 PLUS 1/2(5x+2)

OpenStudy (anonymous):

\[3+ \frac{1}{2}(5x+2)=14\]

OpenStudy (anonymous):

You can substract 3 from both sides of the equation\[\frac{1}{2}(5x+2)=14-3\]

OpenStudy (anonymous):

I think the answer is 4 or -4, not sure...

OpenStudy (anonymous):

You can plug those values and if the equation it's true then it's ok.

OpenStudy (anonymous):

multiplying by 2 both sides of the equation you get: \[5x+2=22\]

OpenStudy (anonymous):

x = 4. You're right
