Question

4. Rozwiąż równania: 5 6 a) c) 2(x - 1) 3 Х X+2 5 = (x+ 8/67 e) -+1 = (x+6) f) *1_X+1 - ) - b) - ** X + 1 4 d) 1- 2x+5 3 = 4 Х 2​

Answer 1

Odpowiedź:

A. x * 6 = 2 * 5

6x = 10

x = 1, (6) ...

B. x * 4 = 2 * (x + 1) =

4x = 2x + 2

4x - 2x = 2

2x = 2

x = 1

C. 5 * 2 (x - 1) = 3 (x + 2)

10 (x - 1) = 3 (x + 2)

10x - 10 = 3x + 6

10x - 3x = 6 + 10

7x= 16

x = 2,285...
