Riya buys 1 book and 2 pencils and pays 2.86. Mia buys 1 book and 1 pencil and pays 1.24. Calculate the cost of 1 book and the cost of 1 pencil

b=-0.38,p=1.62, however, your problem seems broken.

Step-by-step explanation:

1b+2p=2.86

1b+1p=1.24

The only difference between these equations is 1p, and that is equal to 1.62. However, That means that 1b must be negative, which is not possible in the context of the problem. However, I will continue to solve it anyways. b must be equal to -0.38.

However, your problem seems kind of broken.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
