Question

1-x pe 3 -3x-2 pe 2=-6

Va rog ajutati-ma

Answer 1

numitor comun = 3 · 2 = 6 
2 · ( 1 - x )  - 3·( 3x - 2 ) = - 6 · 6 
2 - 2x - 9x + 6 = - 36
- 11x = - 36  - 6 -2 
- 11x = - 44 
x = -  44 : ( - 11 ) = 4

Answer 2

$\displaystyle \frac{1-x}{3} - \frac{3x-2}{2} =-6 \\ 2(1-x)-3(3x-2)=-36 \\ 2-2x-9x+6=-36 \\ -2x-9x=-36-2-6 \\ -11x=-44 \\ x= \frac{-44}{-11 } \\ x=4$
