Mathematics
1 answer:
inna [77]2 years ago
3 0

Answer:

B.

Step-by-step explanation:

Use elimination, or you can plug the answer choices into the eguations. Plugging in the answer choices does take a while though. If you don't know how to do elimination then basically you try to make one of the three values equal to the other in the opposite equation. MAKE SURE TO DO THE FACTOR FOR ALL OF THE VALUES IN THE EQUATION. once you solved it, you then plug in the value back into one of the equations and you find the other value.

The difference of two numbers is 15. The larger number is 1 more than 3 times the smaller number. What are the two numbers?
loris [4]

Answer:

<em>7, 22</em>

Step-by-step explanation:

Let S = the smaller number.

"The larger number is 1 more than 3 times the smaller number."

The larger number is 3S + 1.

The difference between the numbers is 15, so the larger number minus the smaller number equals 15.

3S + 1 - S = 15

2S + 1 = 15

2S = 14

S = 7

The smaller number is 7.

larger number = 3S + 1 = 3(7) + 1 = 21 + 1 = 22

The larger number is 22.
