Question

Am nevoie de ajutor la punctul e.

Answer 1

$(7 \times 9 - x \times 5) - 27 \div 9 = 20$

$(63 - 5x) - 3 = 20 \\ 63 - 5x = 20 + 3 \\ 63 - 5x = 23 \\ 63 - 23 = 5x \\ 5x = 40 \\ x = 40\div 5 \\ x = 8$

Bafta!!!

Answer 2

Răspuns:

(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
