Q) one number is 9 less than three times a second number. If the first number plus twice the second number is 16, find the two numbers.
Answered by Giovanni
So, here's the question in mathematical form:

3x − 9 = y
x + 2y = 16

(34/7, 39/7) is my guess (solved by substitution).

Are there any options?

The textbook answer is x = 5 & y=6 or the other way around.
