ECUACIONES DE PARENTESIS

2(x-1) = -3(2-x)
5(X-1) - 2X = - (-3)
-(X+3)=X-1
-(3X+8)+2(X-1)=5

Answer 1

2(x-1)=-3 (2-x)
2x-2=-6+3x
-2+6=3x-2x
4=X

5 (x-1) -2x=-(-3)
5x-5-2x=3
3x=3+5
3x=8
x=8/3
x= (aproximado ) 2,60

-(x+3)=x-1
-x-3=x-1
-3+1=x+X
-2=2x
-2÷2=X
-1=X
x=-1

-(3x+8)+2 (x-1)=5
-3x-8+2x-2=5
-3x+2x=5+2+8
-5x=15
x=15÷-5
x=-3
