Question

Determina numarul natural x din egalitatea 24+[29-2×(x+1)]=33
Multumesc frumos!!!

Answer 1

24+[29-2×(x+1)]=33

[29-2×(x+1)]=33-24

29-2×(x+1)=9

29-9=2×(x+1)

20=2×(x+1)

x+1=10

x=9

Answer 2

24 + [ 29 - 2 x (X+1)]= 33

29 - 2 x ( X+1) = 33-24

29-2 x ( X+1) =9

2 x ( X+1)= 29-9

2 x( X+1)=20

X+1=20 ; 2

X+1 = 10

X=10-1

X=9
