Answer:

[tex]s\in (-\infty,1)[/tex]

Step-by-step explanation:

Solve the inequality [tex]-2(s - 7) > 4s + 8[/tex]

Use distributive property:

[tex]-2s+14>4s+8[/tex]

Subtract 4s:

[tex]-2s+14-4s>4s+8-4s\\ \\-6s+14>8[/tex]

Subtract 14:

[tex]-6s+14-14>8-14\\ \\-6s>-6[/tex]

Divide by -6 (do not forget to change sign, because division by negative number changes the sign):

[tex]s<1\\ \\s\in (-\infty,1)[/tex]
