(3-1)•(1+x)•(-2)=x
-8x(1+x) = x
-8 - 8x= x
-8x-x = 8
-9x= 8
X= - 8/9
Comprobamos
-8( 1+ (-8/9)) = - 8/9
-8(1 - 8/9)= - 8/9
-8 +64/9= - 8/9
-72/9 + 64/9= - 8/9
-8/9 = - 8/9
2)
3(1-(1-2(1-x)))= -2(x-2)
3( 1 - (1 - 2+2x)) = - 2x +4
3(1 - (-1 +2x) = - 2x +4
3( 1+1 - 2x) = - 2x+4
3(2 - 2x) = - 2x +4
6 - 6x= - 2x +4
-6x +2x= 4 - 6
-4x = - 2
X= 2/4
X= 1/2.
