First you have to simplify the equation. 7m+5m-5 = -5+12m
Then you can add like terms.
12m-5 = -5+12m
Add 5 to both sides
12m = 0+12m
Subtract 12 to both sides
0=0
This equation has infinite solutions
Answer:
The midpoint of a line segment joining (a, b) and (c,d) is given by the formula 
Step-by-step explanation:
If point <em>M </em>in the figure lies midway between points
and
, point <em>M</em> is called the midpoint of segment. To find the coordinates of <em>M</em>, we average the x-coordinates and average the y-coordinates of P and Q.
So the the midpoint of the line segment with endpoints at (a,b) and (c,d) is the point with coordinates of

A lot of money because then they get even more back
Answer:
