Question

2x[3+(c-4)×5]:6×7=7​

Answer 1

Răspuns:

Explicație pas cu pas:

2x[3+(c-4)×5]:6×7=7​

2x[3+(c-4)×5]:6 = 7 : 7 = 1

2x[3+(c-4)×5] = 1 × 6 = 6

3+(c-4)×5 = 6 : 2 = 3

(c-4)×5  = 3-3 = 0

(c - 4) = 0 : 5 = 0

c = 0 + 4 = 4

Answer 2

2 × [ 3 + ( c - 4 ) × 5 ] : 6 × 7 = 7

2 × [ 3 + ( c - 4 ) × 5 ] : 6 = 7 : 7

2 × [ 3 + ( c - 4 ) × 5 ] : 6 = 1

2 × [ 3 + ( c - 4 ) × 5 ] = 1 × 6

2 × [ 3 + ( c - 4 ) × 5 ] = 6

3 + ( c - 4 ) × 5 = 6 : 2

3 + ( c - 4 ) × 5 = 3

( c - 4 ) × 5 = 3 - 3

( c - 4 ) × 5 = 0

c - 4 = 0 : 5

c - 4 = 0

c = 0 + 4

c = 4
