Question

Encontre o valor de X
A)5 (2x-3) =3 (4x-6)

C) x+2 = 2x-1 =???
3 2

Answer 1

Resposta:

Explicação passo-a-passo:

A) 5(2x-3) =3(4x-6)

5*2x = 10x

5*-3 = -15

3*4x = 12x

3*-6 = -18

10x-15 = 12x-18

10x-12x = -18 + 15

-2x = -3    *(-1)

2x = 3

x = 3/2 ou x = 1,5

Answer 2

Encontre o valor de X  

A) 5*(2x - 3) = 3*(4x - 6)

10x - 15 = 12x - 18

12x - 10x = 18 - 15

2x = 3

x = 3/2

C) (x + 2)/3 = (2x - 1)/2

2x + 4 = 6x - 3

6x - 2x = 4 + 3

4x = 7

x = 7/4
