Oblicz, z góry dziekuje

Answer 1

-3(-x - 5) + (4-2x) :2 =3x+15+2-x = 2x+17

 

2(-4x+2) -3 (x-7)=-8x+4-3x+21 = -11x+25

 

-(1-3x) -5 (-x+2) +x=-1+3x+5x-10=8x-11

 

-5(2x+1) - (-x+3) -7 + (x-8)=-10x-5+x-3-7+x-8 = -8x-23

 

4(x-3) - (3x-4) :2 - (9-2,5x) =4x-12-1,5x+2-9+2,5x =5x-19

 

(2x-7)+4(-4+1) *3 -2(x+4)=2x-7-48+12-2x-8=-51
