Answer:

$193.67

Step-by-step explanation:

Let x = shirts

Let y = trousers

Let z = hat

4x + 4y + 2z = 660

9x + 9y + 6z = 1399

Divide the second equation by 3.

3x + 3y + 2z = 466.33

Subtract both equations .

4x + 4y + 2z = 660

3x + 3y + 2z = 466.33

x  +  y = 193.67

So 1 shirt and 1 trouser will be $193.67

krok68 [10]

Answer:

1/3

Step-by-step explanation:

Simplify the following:
