what's all this 121, 122 junk? Guessing?
If the numbers are x and y, just write down what they told you:
x+y = 243
x/2 = 4y
so, x=8y and we have
8y+y=243
9y=243
y=27
so, x=216
The sum of two counting numbers is 243. Half of one number is four times the other
number. What are the numbers?
121.1+122.2=243.2
