Răspuns: [tex]\red{\large\boxed{\bf (a,b) \in \big\{\ (1,~2);~(2,~1) \big\}}}[/tex]
Explicație pas cu pas:
[tex]\bf 24 - [35 - (18-2\cdot a\cdot b: 4)]= 6[/tex]
[tex]\bf 24 - 6 =[35 - (18-2\cdot a\cdot b: 4)][/tex]
[tex]\bf 18 =35 - (18-2\cdot a\cdot b: 4)[/tex]
[tex]\bf 18+ (18-2\cdot a\cdot b: 4)=35[/tex]
[tex]\bf (18-2\cdot a\cdot b: 4)=35-18[/tex]
[tex]\bf 18-2\cdot a\cdot b: 4=17[/tex]
[tex]\bf 18=17+2\cdot a\cdot b: 4[/tex]
[tex]\bf 18-17=2\cdot a\cdot b: 4[/tex]
[tex]\bf 1=2\cdot a\cdot b: 4~~~\bigg|\cdot 4[/tex]
[tex]\bf 4=2\cdot a\cdot b~~~\bigg|:2[/tex]
[tex]\bf 2=a\cdot b \implies \red{\large\boxed{\bf (a,b) \in \{\ (1,~2);~(2,~1) \}}}[/tex]
