5m = 7 + 4m
subtract 4m from both sides
1m = 7
m = 7
=================================
Oops. That first solution lost the '8' from the left side.
An attempt to check the given equation with "m=7" fails.
Try it like this:
5m + 8 = 7 + 4m
Subtract 4m from each side:
m + 8 = 7
Subtract 8 from each side:
m = -1

What does this equal 9m plus 8-4m plus 7-5m?
It is: 9m +8 -4m +7 -5m = 15
How do you solve 5m equals m plus 28?
4m = 28 m = 7 You first put all the "m"s on one side so it becomes 4m = 28 You then divide 28 by 4 and you get 7 I'm not completely sure if it's right
What does the m equals in 8m-5 equals 5m plus 7?
m = 4
What is the value of m in 4m plus 3m equals 180?
4m + 3m = 180 7m = 180 m = 25 5/7
What is m in -4m-7 equals 17?
If: -4m -7 = 17 Then: m = -6
What does this equal 9m plus 8-4m plus 7-5m?
It is: 9m +8 -4m +7 -5m = 15
How do you solve 5m equals m plus 28?
4m = 28 m = 7 You first put all the "m"s on one side so it becomes 4m = 28 You then divide 28 by 4 and you get 7 I'm not completely sure if it's right
What does the m equals in 8m-5 equals 5m plus 7?
m = 4
What is the value of m in 4m plus 3m equals 180?
4m + 3m = 180 7m = 180 m = 25 5/7
What is m in -4m-7 equals 17?
If: -4m -7 = 17 Then: m = -6
What is the answer to 5m plus 7n equals 6.4 2-7n equals 6?
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
2-3m plus 7 equals 4m-9-m-28?
2 - 3m + 7 = 4m - 9 - m - 28 46 = 6m 46/6 = 23/3 = 7.6666 = m
6m plus 7 - 2m plus 1?
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
4m-5 3m plus 7?
The value of m in the equation: 4m-5 = 3m +7 is 12.
What does m equals in this problem 7 equals 2-5m?
m = -1
What is the answer to this math problem 9m equals 4m-35?
If: 9m = 4m-35 Then: m = -7
What does -4m-7 equals 17 ina solving two step equations?
-4m = 24 m = -6
