How much does a hat cost?

Tell the the answer for the T-shirt and hat

Answer 1

Explanation:

Let a hat be x and a t shirt be y.

9y + x = 93.......... (1)

4y + x. = 43...........(2)

Using the elimination method

Multiply eqn (2) by -1 and eqn by +1

9y + x =. 93.........(3)

-4y - x.= -43..........(4)

Add both equations

5y =. 50.......(5)

y. =. 50 ÷5 = 10

y. =. 10

Answer 2

is is 10 for shirt and 3 for hat
