Step-by-step explanation:
Let the first number be a, the second number be b
a+b=17 is the first equation, a-3=4b is the second equation.
From the second equation: a=4b+3
Substituting a=4b+3 into the first equation gives;
5b=14
b=2.8
Substituting b=4 into a=4b+3;
a=4(2.8)+3
a=11.2+3
a=14.2
The numbers are 14.2 & 2.8.
