Question

One number is five more than three times another. If their difference is 35, what is the larger number?
15
50
65

Answer 1

One number is 5 more than three times another ----> 5 + 3x
Another ----> x

Equation would look like:

\( \color{Black}{\Rightarrow (5 + 3x) - x = 35 }\)

Answer 2

Remove the brackets. They're of no use here.

Answer 3

ok

Answer 4

do you still need help?

Answer 5

how do i plug thaat into my calculator to get the answer

Answer 6

Lol you need a calculator for that?

Answer 7

i get 7 otherwise

Answer 8

7? How?

Answer 9

you divided by 5? no no....just combine 5 + 3x - x = 35

Answer 10

What is 3x - x?

Answer 11

3x and -x are common terms so combine them...what do you get?

Answer 12

2x

Answer 13

\( \color{Black}{\Rightarrow 5 + 2x = 35 }\)

What's the next step now?

Answer 14

-5

Answer 15

from both sides

Answer 16

good

Answer 17

what does that give?

Answer 18

2x=30

Answer 19

Yes:

\( \color{Black}{\Rightarrow 2x = 30 - 5}\)

\( \color{Black}{\Rightarrow 2x = 30 }\)

What's next?

Answer 20

divide by 2?

Answer 21

Yes, and what does that give?

Answer 22

GOOD!!!

Answer 23

so x is....?

Answer 24

so u get 5!!!

Answer 25

Now plug in the value of x in 5 + 2x

Answer 26

*15

Answer 27

YOU GOT IT!!!!

Answer 28

5 + 3x

Answer 29

What is \( \color{Black}{\Rightarrow 5 + 3(15) }\)?

Answer 30

^that's to find the larger number

Answer 31

note that 15 is just the smaller number

Answer 32

Yes, because I told in the first post that x is the smaller number and it's written that the larger is 5 more than 3 times the smaller one.

Answer 33

Here, it'd be 5 more than 3 times of 15 which is 5 + 3(15)

Answer 34

8(15)

Answer 35

instead of that since

y - x = 35

and x is 15

y - x = 35

y = 35 + 15

you can use that

Answer 36

No not that one.

Answer 37

you multiply 3 and 15 before adding 5

Answer 38

\( \color{Black}{\Rightarrow (5) + [3(15)] }\)

Answer 39

50

Answer 40

Yes, you got it!

Answer 41
