Solve the equation:
2m + 14 = -8(5 - 7m)
First, we should remove the parentheses by multiplying -8 by its contents:
2m + 14 = -8*5 - (-8)*(7m)
Note the number -8 is now multiplying 5 and 7m
Now we operate individually:
2m + 14 = -40 + 56m
We have multiplied -8 * 7 = -56 and by the sign (-1)
Now we should arrange all the variables to the left side and the numbers to the right side.
Subtracting 56m:
2m + 14 -56m = -40 + 56m - 56m
Canceling like terms in the right side and operating in the left side:
14 -54m = -40
Now subtract 14:
14 -54m - 14 = -40 - 14
Cancel 14 and -14. Operate -40-14=-54:
-54m = -54
