A= $9.90 B= $64.90
because, 18% of $55 is $9.90. Then you would add $9.90 to $55 and get $64.90
The slope is 2 and the y intercept is -5. Graph this line and shade above the line for the solution. :)
Does it want the answer 6/8? I think this is right.

Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.
