solve the equation 7+3m=28 .

A.m=18
B.m=11 2/3
C.m=9
D.m=7

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 = ?

What I do is subtract the first number from the sum, 28-7=21 and go through the answer choices and multiply them by 3, since it is the number right next to m, and whatever gives you 21 is the answer. Example: 28-7=21, 18x3=54, so it's too much. Hope this helps!

Answer a is not correct. Which value for m makes the equation correct?
