Match the following equations to their solutions:

1st -5

2nd 40

3rd -3/8

4th 2

the timing taken to solve each math problem and each biology problem is 4 minutes each respectively

Step-by-step explanation:

Let us assume the timing taken for math problem be x

And, the time taken for biology problem be y

Now as per the question

The following equations should be considered

x + 2y = 14 (1)

2x + y = 16. (2)

Multiply by 2 in equation 1

So,

2x + 4y = 28

2x + y = 16

3y = 12

y = 4 minutes

So, x = 14 - 2(4)

= 12 - 8

= 4 minutes

hence, the timing taken to solve each math problem and each biology problem is 4 minutes each respectively
