2x - 1y = -9
y = - 5 - 5x

x = - 7 and y = 30

Step-by-step explanation:

2x - y = -9

subtract 2x from either side

-y = -9 - 2x

divide either side by -1

y = 9 + 2x

Plug in 9 + 2x for y

9 + 2x = -5 - 5x

Add 5 to either side and subtract 2x from either side

14 = -2x

divide either side by -2

-7 = x

plug in -7 for x in one of the equations

y = -5 - ( 5 x -7 )

y = -5 - ( - 35)

y = -5 + 35

y = 30

plug in x and y

30 = -5 - ( 5 x -7)

30 = -5 - (-35)

30 = -5 + 35

30 = 30

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
