2x - y = 13 ------------- [1]
3x + y = 12 ------------ [2]
Adding both Equations [1] and [2], We get :
⇒ (2x - y) + (3x + y) = 13 + 12
⇒ 2x + 3x - y + y = 25
⇒ 5x = 25
⇒ x = 5
Substituting x = 5 in Equation [1], We get :
⇒ 2(5) - y = 13
⇒ 10 - y = 13
⇒ y = 10 - 13
⇒ y = -3
⇒ (x , y) = (5 , -3)
Option B is the Answer
Let x be the width of the rectangle
Therefore length=3+x
Thus the formula to find the perimeter of the rectangle is:2(3+x+x)
