Question

como se resolve a equação:5(-4x-1)=4x-3(4x-1)-4

Answer 1

5 (-4x -1) = 4x -3 (4x -1) -4
-20x -5 = 4x -12x +3 -4
-20x -4x +12x = 3 -4 +5
-16x +12x = -1 +5
-4x = 4 . (-1)
4x = 4
x= 4/4
x= 1

Bons estudos!

Answer 2

5(-4x-1)= 4x -3(4x-1)-4
-20x-5 = 4x-12x +3-4
-20x-4x+12x = +5+3-4
-24x+12x= +8-4
-12x=+4 (.-1)
12x= -4
x= -4/12
x= -1/3
