X = r - h/y ; Solve for h & r
Let's first solve for h :)
Add h/y to both sides.
h/y + x = r
So, r = h/y + x
Now, let's solve for h.
x = r-h/y
Subtract r from both sides.
-r + x = -h/y
Multiply both sides by y.
y(-r + x) = y(-h/y)
Simplify.
-ry + xy = -h
Divide both sides by -1.
ry - xy = h
So, h = ry - xy

Number one or 2? so i can help you
$149 - $50 = $99
Just subtract the rebate from the cost.
10-4 =6
14x10= 140
