Răspuns:

X-2/3×5/4=5/12

X-1/3×5/2=5/12

X-5/6=5/12

X=5/12+5/6

=》X=5/4

Forma alternativă:

X= 1 întreg 1/4

X= 1,25

Răspuns:

[tex]x = \frac{5}{4 } \\ [/tex]

Explicație pas cu pas:

[tex]x - \frac{2}{3} \cdot \frac{5}{4} = \frac{5}{12} \\ [/tex]

[tex]x - \frac{10}{12} = \frac{5}{12} \\ [/tex]

[tex]x = \frac{5}{12} + \frac{10}{12} = \frac{15 {}^{(3} }{12} = \boxed{\frac{5}{4}} \\ [/tex]
