Answer:

<em>See below</em>

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;

2x - 5 = 4x + 12,\\- 5 = 2x + 12,\\- 17 = 2x,\\\\x = - 17 / 2 = - 8.5\\\\Conclusion, x = - 8.5 / x = - 8 and 1 / 2

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!

Consider -q &gt; 5. Use the addition and/or subtraction property of inequality to solve.
AleksandrR [38]

The correct answer would be -5 > q

In order to solve this using only addition and subtraction, what we need to do is change the side each term is on. This will allow us to get the variable to be a positive number.

-q > 5 ----> Subtract 5 from both sides

-5 - q > 0 -----> Add q to both sides

-5 > q
