Amy and Brad each have some money. Carly has no money.
Amy gives £7 to Carly.
Brad gives £5 to Carly.
Now they all have the same amount of money.
How much money did Amy have to begin with?

Step-by-step explanation:

carly had nothing, amount of money = £0

amy gave her £7 and brad gave her £5,

carly now has £5 and £7

amount of money of carly= £7 + £5

= £12

you are told that they all have the same amount of money and you know that carly has £12. so:

amy has £12, brad has £12 too.

If amy has £ 12 now after giving away £7, then: let x be the initial amount of money amy had,

x - 7 = 12

x = 12 + 7

x = 19

thus, amy had £19.

-s.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
