Question 260483
three times one number equals twice a second number. twice the first number is 3 more than the second number. find the numbers
------------------
Equation:
3A = 2B
2A = B + 3
-----------------------------
Rearrange:
B = 2A - 3
---
Substitute for "B" and solve for "A":
3A = 2(2A-3)
3A = 4A - 6
A = 6 (1st number)
--------
Since B = 2A-3, B = 2*6-3 = 9 (2nd number)
