Question

3x+1/2=x-1 resolva as equações do 1°grau
4x+1/2 + x +3/4 =3x+1/4

Answer 1

Resposta:

Explicação passo-a-passo:

A)

3x+1/2=x-1

3x - x = - 1 - 1/2

2x = (- 2 - 1)/2

2x = - 3/2

4x = - 3

x = - 3/4

B)

4x + 1/2 + x + 3/4 =3x + 1/4

5x - 3x = 1/4 - 3/4 - 1/2

2x = - 2/4 - 1/2

2x = - 1/2 - 1/2

2x = - 2/2

2x = - 1

x = - 1/2
