Answer:
X=3, y=-6
Step-by-step explanation:
7x+4y=-3 equation 1
-7x-5y=9 equation 2
-y=6. Add above two equations
Y=-6
solve for x by inputting y value into either equation.
7x+4(-6)=-3
7x-24=-3
7x=21
x=3
check answer by inputting x and y values into either equation
-7x-5y=9
-7(3)-5(-6)=9
–21+30=9
9=9

Answer:
$285
Step-by-step explanation:
<u>Blueberries:</u>
B = number of pounds of blueberries bought
$5.50 = price of blueberries per pound
$5.50B = total price of B pounds of blueberries
<u>Blueberries:</u>
R = number of pounds of raspberries bought
$4 = price of raspberries per pound
$4R = total price of R pounds of raspberries
<u>Total:</u>
$5.5B + $4R
Since 5.5B+4R=285, then Amit spends in total on both types of berries $285
