40 x $6=$240
<span>6.5 x $9=$58.50 </span>
<span>8 x $ 12=$ 96 </span>
<span>Answer $394.50</span>
Answer:

Step-by-step explanation:

Taking equation (1)

Multiplying both sides by 2

Adding 6y to both sides

Putting this in (2)
5(18+6y) + y = 28
5(18+6y) + y = 28
90 + 30y+y = 28
31y+90-28 = 0
31 y + 62 = 0
31y = -62
Dividing both sides by 31
y = -2
Now,
x = 18 + 6y
x = 18+6(-2)
x = 18-12
x = 6
