Explicație pas cu pas:
24x+36/4x+5 se afla in Z
=> 4x+5 divide 24x+36(1)
si 4x+5 divide 4x+5 inmultim cu 6
=>4x+5 divide 24x+30(2)
scadem pe (2) din (1) si rezulta ca 4x+5 divide 6
deci 4x+5={-6,-3,-2,-1,1,2,3,6}
deci 4x={-11,-8,-7,-6-4,-3,-2,1}
deci x={-11/4,-2,-7/4,-6/4,-1,-3/4,-2/4,1/4}
dar x se afla in Z
deci x={-2,-1}
