\(\Rightarrow200+\left(33600:x\right)-500=7200:4\)
\(\Rightarrow200+\left(33600:x\right)-500=1800\)
\(\Rightarrow33600:x=1800-200+500\)
\(\Rightarrow33600:x=2100\)
\(\Rightarrow x=33600:2100\Rightarrow x=16\)
\(7200:\left(200+\left(33600:x\right)-500\right)=4\)
\(=>200+\left(33600:x\right)-500=1800\)
\(=>33600:x=1800-200+500\)
\(=>33600:x=2100\)
\(=>x=\frac{33600}{2100}\)
\(=>x=16\)
