To solve this problem you
want to use the different properties of numbers
to help you as you move the numbers to find the
solution.
5m - 9 = 41
5m - 9 + 9 = 41 + 9 (You want to add
9 to both sides of the equation. Adding 9 to
the first side will give you -9 + 9 which equals
0 so therefore you have only 5m remaining.
Remember, you want to get m by itself to find
what m equals. Since you added 9 to one side
of the equation you must do the same to the
other side.)
5m - 0 = 50 (Using addition to find
the new numbers on the two sides of the equation.)
5m = 50 (Simplify.)
5m/5 = 50/5 (In order to get m by
itself you want to divide both sides by 5.
The reason is because 5 divided by 5 is 1 on
the first side of the equation. Then you have
1 times m which is just m, which is just what
we want. Just remember to do the same to both
sides of the equation, not just one side.)
m = 10 (Simply.)
Your answer to this problem is 10, which is
given to you as a choice, letter B. Your answer
is letter B. |
