Solve the system of equations.
Ex - 3y = 3
- 2x + y = 14
What number would you multiply the second equation
by in order to eliminate the x-terms when adding to the
first equation?
What number would you multiply the first equation by in
order to eliminate the y-terms when adding to the
second equation?

1/2 and 1/3 respectively.

Step-by-step explanation:

Multiplying the second equation by 1/2 we have;

1/2 ( -2x. + y) = 14 * 1/2

-x + y/2 = 7(3)

From (1); x- 3y =3

Adding eqn( 1) + (3)

( x- 3y =3) + (-x + y/2 = 7)

x-x -3y + y/2 = 3 + 7

-5y/2 = 10;

In order to eliminate y;

Multiplying eqn 1 by (1/3)

We have:

(1/3) (x- 3y= 3)

1/3 x - y =1(4)

eqn(4) + (2)

[1/3 x - y = 1] + [-2x + y = 14]

1/3 x. -2x-y + y = 1 + 14

-5/3 x = 15

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
