Answer:
The number is -2
Step-by-step explanation:
Let the number = x
Given that:
Five times the result of adding one to a certain number, is equal to four times the number, plus three.
The equation will be:
5(x+1) = 4x +3
Simplifying
5x + 5 = 4x +3
Taking terms with x on left side and others on right side
5x - 4x = 3 - 5 (sign of transferred terms will be changed)
x = -2
Proof :
Condition 1:
- Add one = -2 +1 = -1
- Multiply 5 = -5
Condition 2:
- 4 times of number = 4 (-2) = -8
- Add 3 = -8 +3 = -5
Hence both conditions have same answer.
I hope it will help you!

Step-by-step explanation:
Hello
When you have two negative symbols, you have to multiplied them, so:
-*-= +
+*+= +
+*-=-
-*+ = -
You can to do more research lookin this: "Algebraic operations with symbols" or "The sign´s law"
I attached a illustrative image about this.
Then,
5 - (-4) <em>(here is with -*- )</em>
5 + 4
9

8.75 - (3 2/3 + 2 5/8)
8.75 - (11/3 + 21/8)
8.75 - (88/24 + 63/24)
8.75 - 151/24
210/24 - 151/24
