How do you solve #4m=28#?

Answer 1

#m = 7#

When you have an equation, the equality will remain intact if you do the same thing on both sides of the equation.

It's similar to saying that two half-apples will weigh the same if two apples weigh the same since the apples were equal in the first place.

So we have #4m = 28#

Both sides can be divided by 4.

so # (4m)/4 = 28/4 #

so #m = 7#

To solve (4m = 28), divide both sides by 4:

[ m = \frac{28}{4} = 7 ]
