If you have x- + 5 - 13 + 12x, all we are doing is combining like terms. First, 5 - 13 = -8. Then, -x + 12x is the same as doing 12x - x. That gives us 11x. The answer would be 11x - 8 when you put -8 and 11x together in the expression.

What valúe of x solves the equation?<br>5+x-6x=-5

joja [24]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 2}}}}}$

Step-by-step explanation:

$\sf{5 + x - 6x = - 5}$

Collect like terms

⇒ $\sf{5 - 5x = - 5}$

Move 5 to right hand side and change it's sign

⇒ $\sf{ - 5x = - 5 - 5}$

Calculate

⇒ $\sf{ - 5x = - 10}$

Divide both sides of the equation by -5

⇒ $\sf{ \frac{ - 5x}{ - 5} = \frac{ - 10}{ - 5} }$

Calculate

⇒ $\sf{x = 2}$

Hope I helped!

Best regards!!
