Mam problem z wyrażeniami algebraicznymi :
1.-(2x+5)=
2.3(2x+1)=
3.-(3x-1)-(-2x+1)
4.-(4-2x)+2(x-5)=
5.-(x-5)-2(3x-1)=
6. -(2x-1)-2(x+1)=

1.-(2x+5)= -2x - 5
2.3(2x+1)= 6x + 3
3.-(3x-1)-(-2x+1) =-3x + 1 + 2x - 1 = -x
4.-(4-2x)+2(x-5)=-4 + 2x + 2x - 10 = 4x - 14
5.-(x-5)-2(3x-1)=-x + 5 - 6x + 2 = 7 -7x
6. -(2x-1)-2(x+1)=-2x + 1 - 2x - 2 = -4x - 1
