Question

resolver as seguintes equações

1-) 2x - 6 = 0

2-) 2x + 6 = 0

3-) -2x - 6 = 0 ​​

por favor me ajuda​

Answer 1

Resposta:

1) 2x - 6 = 0

2x=6

x=6/2

x=3

2)2x + 6 = 0

2x=-6

x=-6/2

x=-3

3)-2x - 6 = 0

-2x=6

x=6/-2

x=-3

Answer 2

$1) x = 3\\2) x = -3\\3) x = -3$

$1-) 2x - 6 = 0\\ 2x = 6\\ x = 6 / 2\\ x = 3$

$2-) 2x + 6 = 0\\ 2x = -6\\ x = -6 / 2\\ x = -3$

$3-) -2x - 6 = 0\\\\ -2x = 6\ (-1)\\\\ 2x = -6\\\\ x = -6 / 2\\\\\ x = -3$
