For this case we have the following equation:

We apply distributive property on the left side of the equation, taking into account that:

So:

Subtracting 3m from both sides of the equation:

Equal signs are added and the same sign is placed:

We subtract 6 from both sides of the equation:

We divide between -4 to both sides of the equation:

Thus, the solution of the equation is

<h2>Answer:</h2>
The Slope is 
<h2>Explanation:</h2>
Notice that both the points,  and
 and  , are on the line. So we can use those points to calculate the slope. Recall that that slope of the line
, are on the line. So we can use those points to calculate the slope. Recall that that slope of the line  can be calculated by
 can be calculated by  if we have the points,
 if we have the points,  and
 and  .
.

Switching to common denominators, alexa ran 18/24 of a mile. caleb ran 15/24 of a mile. for alexa’s distance, you would do (2•8)+(3•8). for caleb’s distance you would do (5•3)+(8•3). hope this helped!
