Answer:

3x-2= 4x- 6 -x+7 =6x – 14 2x + 5 =45 3•(-3x – 5)=4•(10 – 5x) 6x = 4x + 8 x +5x - 9 =3(2x-3) -(x+1) + 8x = 5x – 9 x +5x - 9 =3(2x-3) 15-2x = 90 0,6(x+2) –(0,4x-0,6) = 0,2(1 - x) 4•(x – 1) + 1 =3•(2x +1) 3x –7=14 - 4x 3• (a+2)-1 =2•(a+3)+a 2 - (a - 3)=3•(a - 2)- 4a 2 - (a - 3)=3•(a - 2)- 4a I think
