Question

Rezolvati in Q ecuatiile:
2(3x-4)-2=3(1-2x)
3(2-3x)+1=6(5x-2)

VA ROG AJUTATIMA MAINE DAU TEZA !!!!!!!!!!! DAU 15 PUNCTE SI COROANA !!!! PLS!!!

Answer 1

Răspuns

Explicație pas cu pas:

2 ( 3 x - 4 ) - 2 = 3 ( 1 - 2 x )

6 x - 8 - 2 = 3 - 6 x

6 x + 6 x = 3 + 10

12 x = 13

x = 13 / 12

_______________

3 ( 2 - 3 x ) + 1 = 6 ( 5 x - 2 )

6 - 9 x + 1 = 30 x - 12

30 x - 12 = - 9 x + 7

30 x + 9 x = 7 + 12

39 x = 19

x = 19 / 39
