Answer 2

Introduction (Kinda)

So you want to write the equation and find the number.

Writing the Equation

Well, the question says "A number s is subtracted from seven. When the result is divided by three, the quotient is two."

If a number s is being subtracted from seven.

7-s

When the result of 7-s is divided by three, the quotient is two. Since your effecting the result of 7-s, you have to put those in parentheses.

(7-s)

Your dividing 7-s by 3.

(7-s) / 3

When you do that, you get 2.

(7-s) / 3 = 2

This is the equation.

Finding the Number

Now you need to solve the equation.

(7-s) / 3 = 2

You need to isolate the s. "Remove" the numbers in opposite PEMDAS order...

Parentheses

7-s is in parentheses.

Divided by 3 is division. So you do that first.

You can multiply by 3 to cancel that out.

(7-s) / 3 × 3 = (7-s)

2 × 3 = 6

7-s = 6

Now that 7-s is on its own side, you can remove the parentheses.

So now to cancel the 7, you subtract 7 from each side (of the equation).

7-s-7 = -s

6-7 = -1

-s = -1

Now to cancel the negative signs, multiply each side by -1.

-s × -1 = s

-1 × -1 = 1

s = 1

Final Answer

The equation is...

(7-s) / 3 = 2

The number is...
