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.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
