Question

solve the equation.

-5y-9=-(y-1)

Answer 1

Which substance has the highest boiling point?

(1 point)

ammonia

water

nitrogen

hydrogen sulfide

Answer 2

To solve the equation, let's simplify each side step by step:

-5y - 9 = -(y - 1)

First, let's distribute the negative sign to the terms inside the parentheses on the right side:

-5y - 9 = -y + 1

Now, let's gather all the y terms on one side and the constant terms on the other side:

-5y + y = 1 + 9

Simplifying further:

-4y = 10

To isolate the variable y, divide both sides of the equation by -4:

(-4y)/(-4) = 10/(-4)

Simplifying further:

y = -10/4

Simplifying the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:

y = -5/2

Thus, the solution to the equation is y = -5/2 or y = -2.5.
