Question

The cost of a sanitizer is Rs 100 more than half the cost of a mask.
The linear equation in 2 variables of this statement is:
(Take the cost of Sanitizer to be Rs.x and cost of the Mask to be Rs.y) *
(2 Points
O 2x+y = 200
O 2x + 2y = 100
O 2r-1-200 = 0
O 2r +- 100 = 0​

Answer 1

Answer:

2x - y = 200

Step-by-step explanation:

Cost of sanitizer = 100 + (half of cost of mask)

Cost of sanitizer is x

Cost of mask is y, so:

= > x = 100 + (1/2 of y )

= > x = 100 + (y/2)

= > x = (2*100 + y)/2

= > 2x = 200 + y

= > 2x - y = 200
