Question

rezolvati in z ecuatiile : -4x+10=10-2x
3(2x-5)+x=6(x-1)-9

Answer 1

○ -4+2x = 10-10 -2x = 0 x = 0:(-2) x = 0 ○ 6x - 15 +x = 6x-6 - 9 7x - 6x = -15 + 15 x = 0

Answer 2

- 4 x + 10 = 10 - 2 x

- 4 x + 2 x = 10 - 10

- 2 x = 0

x = 0

__________

3 ( 2 x - 5 ) + x = 6 ( x - 1 ) - 9

6 x - 15 + x = 6 x - 6 - 9

7 x - 6 x = - 15 + 15

x = 0
