Which is a solution to the equation (10–5y) = 20?

y = -2

Step-by-step explanation:

10 -5y = 20       { subtract 10 from both sides}

  -5y = 20 - 10

  -5y = 10          {Divide both sides by (-5) }

    y = 10/-5

y = -2

16

step-by-step explanation:

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
