\(0.05p-0.02(5-2p)=0.05(p-2)-0.12\)
\(0.05p-0.02(5-2p)=0.05(p-2)-0.12:p\)
\(0.05p-0.1+0.04p=0.05p-0.1-0.12\) \(|Expand \ the \ equation|\)
\(0.09p-0.1=0.05p-0.1-0.12\)
\(0.09p-0.1=0.05p-0.22\)
\(0.09p-0.1-0.05p=-0.22\) \(|Subtract \ 0.05p \ from \ both \ sides|\)
\(0.04p-0.1=-0.22\)
\(0.04p=-0.22+0.1\) \(|Add \ 0.1 \ to \ both \ sides|\)
\(0.04p=-0.12\)
\(0.04p/0.04=-0.12/0.04\) \(|Divide \ both \ sides \ by \ 0.04|\)
\(p=-3\)
\(\star \ Hence \ Solved\)
