Is (–9, –7) a solution to this system of equations? 17x − 19y = –20

x + y = –16

Yes or no
I need help

(-9, -7)

Step-by-step explanation:

To solve this, i used the elimination method.

17x - 19y = -20

x + y = -16

multiply both sides by -17

and that will give you =

17x - 19y = -20

-17x - 17y =272

then i added the equations.

-36y = 252 (divide both sides by -36)

y = -7

now that you have found the y value, the next step is to find the x value and for that you need to pick an equation and solve it.

x + y = -16

x + (-7) = -16 (replace y with -7)

x = -9

(x,y) = (-9, -7)

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
