Answer 1

Explanation:

the answer is actually t shirts =9 and hat = 4

Answer 2

T shirt = £9

Hat = £5

Explanation:

1)

Let cost of T-shirt be x

7x + y = 67

y = 67 - 7x

2)

5x + y = 49

Substituting

5x + (67-7x) = 49

67 - 2x = 49

-2x = -18

x = 9

To find y

7x + y = 67

7*9 + y = 67

y = 68-63 = 5
