Abuilding has a total of 60 one-bedroom and two-bedroom apartments. there are twice as many one-bedroom apartments as two-bedroom apartments. how many apartments of each type are in the building? use a system of linear equations to justify your answer.

Number of one bedroom apartment is 40 and two bedroom apartment is 20.

Step-by-step explanation:

Let x be the number of one bedroom apartment

and y  be the number of two bedroom apartment

According to the question,

x + y = 60 (1)

x = 2y (2)

Put value of x from equation (2) in equation (1),

2y + y = 60

3y = 60

y = 20

⇒ x = 2 × y = 2 × 20 = 40

Therefore, Number of one bedroom apartment is 40 and two bedroom apartment is 20.

step-by-step explanation:

just plug in each number for x and see which ones work and don't
