Question

Folosind metoda mersului invers
numarul natural x din egalitate
[(x-8): 2² +3] . 2 = 22​

Answer 1

[( x - 8 ) : 4 + 3] ×2 = 22

[( x - 8 ) : 4 + 3] = 22 : 2

[ x - 8 ) : 4 + 3] = 11

( x - 8 ) : 4 = 11 - 3

( x - 8 ) : 4 = 8

( x - 8 ) = 8 × 4

x - 8 = 32

x = 32 + 8

x = 40

2^2 = 2×2 = 4
