Question

What is the answer? Please help!!!!

Answer 1

Purse £14
Watch £13

I just subtracted 27 from 41 and found the difference was 14 meaning that the purse was 14 because that was the only difference in the equations. Then I subtracted 14 from 27 to take out the price of the purse to find the price of the watch.

Answer 2

a) 14

b) 13

Explanation:

P= Purse W= Watch

1P + 1W = 27 (So think about different combinations that make 27)

2P + 1W = 41 (Multiply this by negative 1)

So now you have

1P + 1W = 27

-2P - 1W = -41

You can subtract them

-1P = -14 or 1P = 14

So 1 purse = 14

Now plug it in

14 + 1W = 27 (Subtract 14 from both sides)

1W = 13

So 1 watch = 13

Furthermore, 1 watch = 13 and 1 purse = 14
