Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k =
= 
y =
x ← equation of variation
When x = 5, then
y =
× 5 = 
X=0
-23 = x - 23
Step 1 cancel equal terms on both sides of the equation
0=x
Step 2 swap the sides of the equation
x=0
Answer:
20
Step-by-step explanation:
x = price
y = number of keyboard
xy = 540
(x-2)(y+3) = 540
x = 540/y
==> x = 20
==> y = 27
