Let's solve ~

$\qquad \sf \dashrightarrow \: - 10 + 5(78 + 8) < - 4s + 3 - 8$

$\qquad \sf \dashrightarrow \: - 10 + 5(86) < - 4s - 5$

$\qquad \sf \dashrightarrow \: - 10 +430 < - 4s - 5$

$\qquad \sf \dashrightarrow \: 420 + 5 < - 4s$

$\qquad \sf \dashrightarrow \: 42 5 < - 4s$

$\qquad \sf \dashrightarrow \: 42 5 \div 4 < - s$
