Question 1

Solve the following inequality for s. Write your answer in simplest form.

-10 + 5(78 + 8) < - 4s +3 - 8

Question 2

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

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

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

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

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

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

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

$\qquad \sf  \dashrightarrow \: 106.25 < - s$

Inequalities change when it is multiplied by -ve number

$\qquad \sf  \dashrightarrow \: - 106.25 > s$
