Question

12. Simplify : 2x - (5y -(x-2y)) and find the value of expression when x = 2.y =1
​

Answer 1

Answer:

simplified form is 3x-3y

Step-by-step explanation:

when putting X=2,y=1 we get

3×2-3×1= 6-3=3

3 is the ans.

good night and sweet dreams.

Answer 2

⟹ 2x-(5y-(x-2y))

⟹ 2x-(5y-x+2y)

⟹ 2x-(7y-x)

⟹ 2x-7y+x

⟹ 3x-7y. [ now apply the values x= 2; y= 1]

⟹ (3×2)-(7×1)

⟹ 6-7

⟹ (-1) Ans.
