45x is the answer to your question
-3s-5=4 First add 5 to both sides of the equal sign to cancel out -5
+5 +5 You're left with -3s=9
-3s=9 Divide by -3 on both sides. This cancels out the -3s. 9 divided by -3 equals -3. The answer would be s=-3
8u+3<19 subtract 3 from both sides
8u<16 divide both sides by 8
u<2 so
-9 is in the solution set u=(-oo, 2)
