x - 5/4 = 3

OpenStudy (anonymous):

\[\frac{x-5}{4}=3\] multiply both sides by 4\[\frac{4}{1}*\frac{x-5}{4}=\frac{4}{1}*\frac{3}{1}\]

OpenStudy (anonymous):

on the left side you can see that the 4's cancel each other and multiplying the right side leaves you\[\frac{x-5}{1}=\frac{12}{1}\] a numerator over 1 is simply the numerator which leads to \[x-5=12\]

OpenStudy (anonymous):

so then i have \[4x - 20/ 1 = 12/1 ?\]

OpenStudy (anonymous):

oh right

OpenStudy (anonymous):

add 5 to both sides so that you don't manipulate the equation \[x-5+5=12+5\] x=17

OpenStudy (anonymous):

so x = 17

OpenStudy (anonymous):

check put x=17 into the equation

OpenStudy (anonymous):

haha ok thank you very much!

OpenStudy (anonymous):

\[\frac{17-5}{4}=3=\frac{12}{4}\]

OpenStudy (anonymous):

it's correct

OpenStudy (anonymous):

Appreciate it, gave you medal
