I think this is it x-y÷2=x+y÷4
X=2 for the top & for the bottom 3/4y+15/4
Answer:
$9.84
Step-by-step explanation:
at 45% off the case is $5.41
Therefore this $5.41 is only 100% - 45% = 55% of the original price
x = original price

55/100 x = 5.41
x = 5.41 * 100 / 55
x = $9.84
Answer:

= 7x² + 4y²
b) = (8 - 5) x + (3 + 4) xy - 7
= 3x + 7xy - 7
