Explicație pas cu pas:
[tex]5 + 3 \times \{35 - 2 \times [4 \times a - (35 \div 5 - 2 \times 3)] + 2 \} \div 5 = 14 \\ [/tex]
[tex]3 \times \{35 - 2 \times [4 \times a - (7 - 6)] + 2 \} \div 5 = 14 - 5 \\ [/tex]
[tex]3 \times [35 - 2 \times (4 \times a - 1) + 2] \div 5 = 9 \\ [/tex]
[tex]3 \times [35 - 2 \times (4 \times a - 1) + 2] = 9 \times 5 \\[/tex]
[tex]35 - 2 \times (4 \times a - 1) + 2 = 45 \div 3[/tex]
[tex]2 \times (4 \times a - 1) = 37 - 15[/tex]
[tex]2 \times (4 \times a - 1) = 22[/tex]
[tex]4 \times a - 1 = 22 \div 2[/tex]
[tex]4 \times a = 11 + 1[/tex]
[tex]4 \times a = 12[/tex]
[tex]a = 12 \div 4[/tex]
[tex]a = 3[/tex]
