Question

resouva as equações :4×-1=3 (-1)

Answer 1

-4x+1=-3
-4x=-3-1
-4x=-4
x=-4/4
x=1

Answer 2

Resposta:

x=- 1/2

Explicação passo-a-passo:

$4x - 1 = 3( - 1) \\ 4x - 1 = 3 \times ( - 1) \\ 3 \times ( - 1) \\ - (3 \times 1) \\ - 3 \\ 4x - 1 =3 \times ( - 1) \\ 4x - 1 = - 3 \\ 4x - 1 + 1 = - 3 + 1 \\ 4x = - 3 + 1 \\ 4x - 1 = - 3 \\ 4x = - 3 + 1 \\ - 3 + 1 \\ - (3 - 1) \\ - 2 \\ 4x = - 3 + 1 \\ 4x = - 2 \\ 4x \div 4 = - 2 \div 4 \\ x = - 2 \div 4 \\ 4x \div 4 = - 2 \div 4 \\ x = - \frac{2}{4} \\ x = - \: \frac{ \cancel2}{ \cancel4} \\ x = - \frac{1}{2} \\ 4x = - 2 \\ x = - \frac{1}{2} \\ resposta \\ \red{x = - \frac{1}{2}}$
