Answer:
-7
Step-by-step explanation:
So to start we know we are adding the two numbers to get something that is less than -11. They give us both numbers (3 and twice s). The twice a number,s, just means the variable they want you to use is s and its multiplied twice. Since we only need a single possible value we can just set it equal to -11.
3+2s= -11 First subtract the 3 from both sides.
-3 -3
2s=-14 Now divide by 2 to get s alone.
