The answers are that the number can equal -4 or 1.
You can find this by setting the number equal to x.
x^2 (The square of a number) + 3x (three times a number) = 4
x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0
Then you can factor this to find the answers
(x - 4)(x + 1) = 0
Set both equal to 0 and solve.

Answer:
x = -3
Step-by-step explanation:
2(x+4)=-7-3x
Distribute
2x+8 = -7-3x
Add 3x to each side
2x+3x+8=-7-3x+3x
5x +8 = -7
Subtract 8 from each side
5x+8-8 = -7-8
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
