Yay! You are welcome.
Thank you miss sue
Thanks miss sue you made it easier for me it is 7
Thanks Ms. Sue! <3
To solve the equation 7 + 3m = 28, we want to isolate the variable, m, on one side of the equation. Here's how you can do it step by step:
1. Start with the equation: 7 + 3m = 28.
2. To get rid of the constant term on the left side of the equation, subtract 7 from both sides:
7 + 3m - 7 = 28 - 7
3m = 21.
3. Now, we want to get m by itself. Since 3 is multiplied by m, we need to divide both sides of the equation by 3:
(3m) / 3 = 21 / 3
m = 7.
Therefore, the solution to the equation 7 + 3m = 28 is m = 7.
Hence, the answer is D. m = 7.
I think a
Then its not 21 and 21 is the awnser for 3m
7+3m=28
Subtract 7 from both sides.
3m = 21
Divide both sides by 3
m = 21/3
m = ?
