Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

$\frac{x}{y}=\frac{3}{4}$

$y=\frac{4}{3}x$ -----> equation A

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

substitute equation A in equation B

$x+\frac{4}{3}x=35$

$\frac{3x+4x}{3}=35$

$\frac{7}{3}x=35$

$x=35*3/7=15$

$y=35-15=20$
