Question

valor da expressao 5-4(x-1)=4x-3(4x-1)-4

Answer 1

Olá,

Vamos lá,

5-4(x-1)=4x-3(4x-1)-4
5-4x +4= 4x -12x +3-4
-4x-4x+12x = + 3 - 4 -5 -4
4x = -10
x = - 10/4
x = - 2,5

Answer 2

5 - 4 (x - 1) = 4x - 3 (4x - 1) - 4
5 - 4x + 4 = 4x - 12x + 3 - 4
-4x - 4x + 12x = 3 - 4 - 5 - 4
-8x + 12x = -10
4x = -10
x = -10/4
x = -5/2
