Three times a number, less twice the number and 9 is 17. What is the number?

1 answer:

7 0

I believe your answer is 8.

Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17

Solve for n as follows:

3n - 2n = n

n + 9 = 17

17 - 9 = 8

Hope this helps! :)

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan?

The first statement means:

b=i+12,

The third statement means:

b-3=4(i-3),

b-3=4i-12

b=4i-9

Using the value for b from the first statement in the third statement gives you:

i+12=4i-9

-3i=-21

i=7: and since b=i+12

b=19

So Ben is 19 and Ishaan is 7.
