PLS HELP ASAP NEED FOR A TEST

Which equation can be used to find the two numbers whose ratio is 3 to 4 and that have a sum of 35


A 3x + 4X equals 35

B 3 / 5x equals 35

C 4 x - 3x equals 35

D 4 / 3x equals 35

Answer 1

The answer in the procedure

Explanation:

Let

x----> the first number

y----> the second number

we know that

`(x)/(y)=(3)/(4)`

so

`y=(4)/(3)x` -----> equation A

`x+y=35` ----> equation B

substitute equation A in equation B

`x+(4)/(3)x=35`

`(3x+4x)/(3)=35`

`(7)/(3)x=35`

`x=35*3/7=15`

`y=35-15=20`
