Hi there!
Since both 4x and 20 can be divisible by 4 and is greatest able to be divisible by 4, we can divide the 4 and put it outside of the parenthesis in order to factor:
4x / 4 = x
20 / 4 = 5
4 (x + 5)
would be your answer.
Hope this helps!
Answer:
Let the number be n.
3n - 4= -15

3n= -11
n= -11/3
n= -3.67 or n= -3 2/3
Step-by-step explanation:
