A+b=302
a=3b/4

3b/4+b=302. Amplif cu 4

3b+4b=1208
7b=1208
b=172.57

a=172.57*3/4=129.42

X= primul numar
302-x = al doilea numar
x=\dfrac34(302-x)

4x=906-3x

7x=906

x=\dfrac{906}{7}=129\dfrac37 primul numar

Al doilea numar este 302-\dfrac{906}{7}=\dfrac{2114-906}{7}=\dfrac{1208}{7}=172\dfrac47
