Answer:
3
Step-by-step explanation:
Say Jill picks the number x.
She multiplies it by 2 giving 2x.
It says add 5 to that product giving 2x+5.
She multiplies this sum by -3 giving -3(2x+5).
She then subtracts 7 from that product giving -3(2x+5)-7.
Her number after doing all of this is -40 so we hae -3(2x+5)-7=-40
To solve:
First: I would add 7 on both sides: -3(2x+5)=-33
Second: I would divide boht sides by -3: 2x+5=11
Third: I would subtract 5 on both sides: 2x=6
Last: I would divide both sides by 2: x=3
