m – 12 = 20

Step-by-step explanation:

We see "equals 20", so we can automatically write:

= 20

Whenever something says "than", that means the two things they're saying need to be flipped. For example, 5 less than 1 would be 1 - 5.

So "12 less than a number m" would be m – 12.

Putting it all together would be:

m – 12 = 20
