So the first step to solving this problem is to distribute the
![\frac{1}{4}](/tpl/images/0403/6527/09cb7.png)
to what's inside the parenthesis. This means multiply
![\frac{1}{4}](/tpl/images/0403/6527/09cb7.png)
by 4x and 15.
After that, this is what you shoud have.
![\frac{4x}{4}](/tpl/images/0403/6527/7c3e7.png)
+
![\frac{15}{4}](/tpl/images/0403/6527/b4a38.png)
= 24
This should be simplified
1x = 24 -
![\frac{15}{4}](/tpl/images/0403/6527/b4a38.png)
![\frac{15}{4}](/tpl/images/0403/6527/b4a38.png)
is equal to 3.75
x = 20.25
20.25 is equal to
![\frac{81}{4}](/tpl/images/0403/6527/ea43d.png)
