Write the equation

100

twice a number (n) is 12

2n = 12 so n=6

200

9 more than 4 times a number (a) is 25

4a + 9 = 25 

300

the quotient of a number (y) and 3 is 6

y/3 = 6 so y= 18

400

6 less than the product of a number (m) and 3 is 21

3m - 6 = 21

500

4 increased by the quotient of (a) and 5 is 12

a/5 + 4 = 12 or 4 + a/5 =12
