To find out how far Raul ran, we need to find our system of equations.
I will rewrite the question entirely. While I do that, I will translate in parenthesis the equation.
Hailey (H) ran (=) 12 km (12).
This is (H=) 3 times farther than Raul (3R).
Now, let's write what's only in parenthesis.
H = 12
H = 3R.
Since H = 12, substitute 12 for H.
12 = 3R is now our remaining question.
To find what R is, we need to take not that R is being multiplied by 3. To get R by itself (solve), we need to get rid of the 3.
One way to get rid of the 3 is to divide by 3.
The other way is to multiply by 1/3.
Remember, what you do to one side of the equation, you must do to the other side as well.
We'll make this simple, divide both sides by 3.
12 / 3 = 4.
3R / 3 = R
R = 4.
Your answer is:
Raul ran 4km.
I hope this helps!
