Question

3x 3+3:3 + 3 x (a:3-3) = 2 020​

Answer 1

Răspuns: 2019

Explicație pas cu pas:

3 × 3 + 3 : 3 + 3 × (a : 3 - 3) = 2020​

9 + 3 : 3 + 3 × (a : 3 - 3) = 2020​

9 + 1 + 3 × (a : 3 - 3) = 2020​

10 + 3 × (a : 3 - 3) = 2020​

3 × (a : 3 - 3) = 2020​ - 10

3 × (a : 3 - 3) = 2010

(a : 3 - 3) = 2010 : 3

a : 3 - 3 = 670

a : 3 = 670 + 3

a : 3 = 673

a = 673 × 3

a = 2019
