4( 1 - 5 x ) + 2 ≤ 166

Answer 1

`{ \qquad\qquad\huge\underline{{\sf Answer}}}`

Here we go ~

`\qquad \sf  \dashrightarrow \: 4(1 - 5x) + 2 \leqslant 166`

`\qquad \sf  \dashrightarrow \: 4 - 20x + 2 \leqslant 166`

`\qquad \sf  \dashrightarrow \: - 20x + 6\leqslant 166`

`\qquad \sf  \dashrightarrow \: - 20x \leqslant 166 - 6`

`\qquad \sf  \dashrightarrow \: - 20x \leqslant 160`

`\qquad \sf  \dashrightarrow \: - x \leqslant 160 / 20`

`\qquad \sf  \dashrightarrow \: - x \leqslant 8`

`\qquad \sf  \dashrightarrow \: x \geqslant 8`

[ Inequality changes as we multiply -1 on both sides ]
