4 = 2 * 2
Multiplying by 2 is the same a doubling.
Since 4 is 2 * 2, to multiply a number by 4, double the number twice.
Example:
What is 4 * 100?
Double 100 to get 200.
Double 200 to get 400.
Therefore, 4 * 100 = 400.
By doubling twice, we do the same as multiplying by 4.

there you go just a copy and a paste
X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
Answer:
I think it is 1 and 4 :))
Step-by-step explanation:
I hope so it will helpful for u
The first part is addition.
45+m
If she spend a third of it, you could multiply by 1/3 or divide by 3.
