4) 4x + 3y = 56<br> 2x + y = 24<br> Solve using elimination please show work

lesya [120]

Answer:

x = 8 y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now 4x + 3y = 56

-2x = -16

x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check: Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56 So we have the correct values for x and y

brooklyn bought 8 bags of the same dog food. She has a $5 coupon. She spent $91. How much was each bad of dog food?

blsea [12.9K]

Answer:

$12

Step-by-step explanation:

Hi there!

What we know:

Brooklyn bought 8 bags of dog food
Brooklyn also used a $5 coupon
The total was $91

Therefore, 8 × (cost of 1 bag) - 5 = 91

Form an equation with x as the cost of 1 bag of dog food:

8 × (cost of 1 bag) - 5 = 91

$8x-5=91$

Add 5 to both sides

$8x-5+5=91+5\\8x=96\\$

Divide both sides by 8

$\frac{8x}{8} = \frac{96}{8} \\x=12$

Therefore, 1 bag of dog food costs $12.

I hope this helps!
