Solve the system by the elimination method. -2x + y + 6 = 0 2x + y - 8 = 0 When you eliminate x, what is the resulting equation?

Natali5045456 [20]

For this case we have the following system of two equations with two unknowns:

$-2x + y + 6 = 0\\2x + y-8 = 0$

Adding both equations we have to eliminate the variable "x":

$y + y + 6-8 = 0$

Adding common terms, keeping in mind that different signs are subtracted and the sign of the major is placed:

$2y-2 = 0\\2y = 2$

Answer:

$2y = 2$

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

$Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455$
