-{-2-(15-x)-10}-[-(50x-18x+49)]-2=-{-[(35x-10)+1]-1}+15 rapido porfavor

Answer 1

-{-2-(15-x)-10}-[-(50x-18x+49)]-2=-{-[(35x-10)+1]-1}+15=

2-(15-x)-10+50x-18x+49-2=-(-{(35x-10)+1])-1+15=

2-(-x+15)-10+32x+49-2=-(-{(35x-10)+1])-1+15=

2-(15-x)-10+32x+49-2=35x-10+1-1+15=

2-(15-x)-10+32x+49-2=35x+5

33x+24=35x+5

33x+24-24=35x+5-24

33x=35x-19

33x-35x=35x+19-35x

-2x=-19

-2x/2=-19/-2

x=19/2
