are you familiar with PEMDAS?
OpenStudy (anonymous):
yeah
OpenStudy (anonymous):
okay (: so first, you would multiply 6 by 4, then add 5 to that, and you have your answer!
OpenStudy (anonymous):
29?
OpenStudy (anonymous):

Is the problem \[
\Large \frac x4 - 5 = 6
\]?
OpenStudy (anonymous):
yeah
OpenStudy (aum):
x / 4 - 5 = 6
To solve for x, first isolate x.
To do that add 5 to both sides:
x / 4 = 6 + 5
x / 4 = 11
multiply both sides by 4
x = 44
OpenStudy (aum):
And you can quickly verify the answer x = 44 is correct:
44/4 - 5 = 11 - 5 = 6

^but wouldnt you have to multiply before you add?

No. PEMDAS does not apply here.
The problem here is not the order of operations.
It is an equation where we have to solve for x.
To solve for x we have to isolate x first.
Step 1. Add 5 to both sides.
Step 2. Multiply both sides by 4.
