Solve for R<br><br> 3 r + 4 <br> ---------- = 5 <br> 2<br><br> r = ?
lakkis [162]
To find r, first write out the equation:
\frac{3r+4}{2} =5
Next, multiply both sides by 2:
3r+4=10
Now, subtract both sides by 4:
3r = 6
Divide both sides by 3:
r=2

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!
