One number is 3 less than twice another. If their sum is 39 find the numbers
1 answer:
Answer:
The numbers are 14 and 25
Step-by-step explanation:
Let one of the numbers be x. The second number we are told is 3 less than twice x. The second number will thus be;
2x - 3
The sum of the numbers is thus;
x + (2x - 3) = 3x - 3
But the sum of the numbers is said to be 39, therefore;
3x - 3 = 39
3x = 42
x = 14
The second number is thus;
2(14) - 3 = 28 - 3 = 25
