Let us assume the unknown number to be = x
Then, based on the information's already given in the question the equation can be written as
7x - 12 = 16
7x = 16 + 12
7x = 28
x = 28/7
= 4
So from the above deduction we can conclude that the unknown number in the question is 4. I hope the procedure is simple enough for you to understand.You can always use this method in future for solving similar problems.
You have the following function:
2x + 4 = 8
in order to solve the prvious equation for x, as follow:
2x + 4 = 8 subtract 4 both sides
2x = 8 - 4
2x = 4 divide by 2 both sides
x = 4/2
x = 2
Hence, the solution for x is 2
Pick a number: 5
Add 7: 5+7=12
Triple the result: 12*12*12=1728
Add 9= 1728+9=1737
Divide by 3 = 1737/3=579
Subtract original number = 579-5=574
Now pick a different number a do the same process
Hope that helps
Answer:
A
Step-by-step explanation:
Because there is three points ABC
The answer is x is less than and equal to 8. Treat the sign as an equal sign.
