Question

Solve the equation for x -x = 5 - 7x - 17

Answer 1

Answer:

x = -2

Step-by-step explanation:

$- x = 5 - 7x - 17$

$- x = - 12 - 7x$

$- x + 7x = - 12$

$6x = - 12$

$x = - 2$

Answer 2

Answer:

$x=-2$

Step-by-step explanation:

$-x=5-7x-17$

⇨ Group like terms:-

$-x=-7x+5-17$

⇨ Subtract 5-17=-12:-

$-x=-7x-12$

⇨ Add 7x from both sides:-

$-x+7x=-7x-12+7x$

$6x=-12$

⇨ Divide both sides by 6:-

$\frac{6x}{6}=\frac{-12}{6}$

$x=-2$
