Use the proportion formula:
5mm/32= Xmm/160
=22.22 mm
-2xy+3x-2xy+3x
-2xy-2xy+3x+3x ( combine like terms)
-2xy-2xy=-4xy
3x+3x=6x
-4xy+6x
Answer: B. -4xy+6x
The relationship between the cost of books and pens is an illustration of linear equation.
The linear equation is (a) 
From the question, we have:
x exceeds 2 times y by 10
Rewrite as:
x exceeds 2y by 10
Exceed means plus (+)
So, we have:

Equate the above equation to 0

Hence, the required equation is (a)
