Question

Aflați x din 2x plus 4 pe 4 este egal cu x plus 11 pe 3​

Answer 1

Răspuns:

2x + 4/4 = x + 11/3

4/4 = 4:4 = 1

2x + 1 = x + 11/3

11/3 = 11:3 = 3,66

2x + 1 = x + 3,66

2x = x + 2,66

2x-x = 2,66

x = 2,66

sau

2x + 4/4 = x + 11/3

(4 * 3) / (4 * 3) = 12/12

(11 * 4) / (3 * 4) = 44/12

2x + 12/12 = x + 44/12

2x = x + 44/12 - 12/12

2x = x + 32/12

x = 32/12

x = 32:12

x = 2,66
