Step-by-step explanation:
In this example we are to consider the equation 2x - 5 = 4x + 12, and are asked to solve for x. Well let us take the first approach, a mathematical one;

Now consider the explanation, " talking over a phone to a friend. "
First you would subtract 2x on either side of the equation, canceling the 2x on one side, and subtracting 2x from 4x on the other, resulting in the simplified equation - 5 = 2x + 12. Subtracting 12 from either side we cancel the 12 on one side, and subtract - 12 and - 5 on the other. We now get - 17 = 2x. Dividing 2 on either side, x = - 8.5!
Answer:
To add fractions there are Three Simple Steps:
Step-by-step explanation:
Step 1: Make sure the bottom numbers (the denominators) are the same.
Step 2: Add the top numbers (the numerators), put that answer over the denominator.
Step 3: Simplify the fraction (if needed)
1 plus to the negative Peter plus the relative integers
I would choose the formula D (distance to the finish line)=3-2x/2 where x is the distance run so for example for x = 1 km then 2 times 1 = 2/2=1 so D=3-1=2km which is seen to be the logical answer so it seems to corroborate the equation.
