Question

Află valoarea lui ''y'' din egalitatea:
2 x [14+(5+y):6] :8+7=11

Mulțumesc anticipat!

Answer 1

2x[14+(5+y):6]:8=11-7
2x[14+(5+y):6]:8=4
2x[14+(5+y):6]=4x8
2x[14+(5+y):6]=32
[14+(5+y):6]=32:2
[14+(5+y):6=16
[14+(5+y)=16x6
[14+(5+y)=96
5+y=96-14
5+y=82
y=82-5
y=77

Answer 2

2 ·[14+(5+y) :6] :8+7 egal 11
2·[14+(5+y) :6] :8 egal 11-7
2·[14+(5+y) :6] :8 egal 4
2·[14+(5+y) :6] egal 4·8
2·[14+(5+y) :6] egal 32
[14+(5+y) :6] egal 32:2
[14+(5+y) :6] egal 16
[(5+y) :6] egal 16-14
(5+y) :6 egal 2
(5+y) egal 2·6
5+y egal 12
y egal 12-5
y egal 7
