Question

Ecuasión 5×-2(×-6)=9-2+2(×-1)​

Answer 1

Respuesta:

x = -7

Explicación paso a paso:

5x  - 2(x - 6) = 9 - 2 + 2(x - 1)​

5x - 2x + 12 = 9 - 2 + 2x - 2

3x + 12 = 5 + 2x

3x - 2x = 5 -  12

        x = -7

Comprobamos

5x  - 2(x - 6) = 9 - 2 + 2(x - 1)​

5(-7) - 2(-7 -6) = 9 - 2 + 2(-7 - 1)

-35 - 2(-13) = 7 + 2(-8)

-35 + 26 = 7 (-16)

         -9 = -9
