6 0

Step-by-step explanation:

4x + y = 6 => 8x + 2y = 12.

8x + 2y = 12

+ (-5x - 2y = -3)

=> 3x = 9, x = 3.

Therefore 4(3) + y = 6, 12 + y = 6, y = -6.

The solutions are x = 3 and y = -6.

Question 5 of 6

Dmitry [639]

Answer:

B. 13 small bags and 12 large bags

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of small bags.

y is the number of large bags.

The Tuesday morning delivery consists of 25 bags

This means that $x + y = 25$ , that is $y = 25 - x$

Bunyan Farm sells 3 pound and 5 pound bags of onions. Total of 99 pounds.

This means that $3x + 5y = 99$

Since $y = 25 - x$

$3x + 5(25 - x) = 99$

$3x + 125 - 5x = 99$

$-2x = -26$

$2x = 26$

$x = \frac{26}{2}$

$x = 13$

$y = 25 - x = 25 - 13 = 12$

So 13 small bags and 12 large bags.
