Question

Rezolvati in Z. 2(2x-9) - 5(x+2)=6(7 - 2x)-26

Answer 1

2(2x-9) - 5(x+2)=6(7 - 2x)-26

4x - 18 - 5x - 10 = 42 - 12x - 26

- x - 28 = - 12x + 16

- x + 12x = 16 + 28

11x = 44  l:11

11x/11 = 44/11

x = 4

Answer 2

2(2x-9)-5(x+2)=6(7-2x)-26

4x-18-5x-10=42-12x-26

-x-28=12x+16

-x=-12x+16+28=-12x+44

-x+12x=44

11x=44

$x = \frac{44}{4} = 11$
