[tex](7 \times 9 - x \times 5) - 27 \div 9 = 20[/tex]
[tex](63 - 5x) - 3 = 20 \\ 63 - 5x = 20 + 3 \\ 63 - 5x = 23 \\ 63 - 23 = 5x \\ 5x = 40 \\ x = 40\div 5 \\ x = 8[/tex]

(63 - 5x) - 3 = 20 \\ 63 - 5x = 20 + 3 \\ 63 - 5x = 23 \\ 63 - 23 = 5x \\ 5x = 40 \\ x = 40\div 5 \\ x = 8\end{gathered}
(63−5x)−3=20
63−5x=20+3
63−5x=23
63−23=5x
5x=40
x=40÷5
x=8
sper ca team ajutat
