The easiest way to calculate this, since you don't need to know what the discount is, if the decrease is 4% you still have 96%.
Multiply 29,000 x .96= $27,840.
If you do it the other way, .04 x 29000= 1160. Then subtract 29000-1160=27850.
-3x - y = -17
4x + 2y = 20
multiply one part of the equation so that we can be able to use the process of elimination.
(-3x - y = -17)2
4x + 2y = 20
Now we have:
-6x -2y = - 34
4x+2y= 20
------------------------
-2x = -14
Divide -2 on both sides.
-2x = -14
/-2 /-2
x = -7.
=============================================
To solve for y, we just have to substitute the value of x to any of the equation given above, that we feel comfortable with. And I'm going to choose this equation: 4x + 2y = 20
4x + 2y = 20
4(-7) + 2y = 20
-28 + 2y = 20
Add 28 on both sides
-28 + 2y = 20
+28 +28
---------------------
2y = 48
/2 /2
y = 24.
The last thing you would do is to check if the answers is correct.
All you have to do is plug in the values of x and y into both equations and see if they equal to one another.
You may have to do this by yourself :P

This would be point-slope form.
Slope-intercept form is in the form: y = mx + b
Standard is in the form ax + by = c
Point-slope form is in the form y - y.1 =m(x - x.1)
The form this most closely resembles is point-slope.
