Answer:

maybe

Step-by-step explanation:

If p is prime, then answer is NO. If p is not prime, the answer is YES.

Some positive integers are prime; some are not. We need to know more about p before we can give a better answer than this.

If you were to solve the system using the addition method, what would you multiply the first equation by in order to make the x'

Inessa05 [86]

2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get

-4x+6y=12
4x-2y=8 +
0x+4y=20

4y=20
y=5

sub back
-2x+3y=6
-2x+3(5)=6
-2x+15=6
-2x=-9
x=9/2=4.5

the number to multiply by is 2

Answer:

$\frac{31x}{30}$

Step-by-step explanation:

Before adding we require the fractions to have a common denominator

The lowest common denominator of 2, 5 and 3 is 30, thus

$\frac{15x}{15(2)}$ + $\frac{6x}{6(5)}$ + $\frac{10x}{10(3)}$

= $\frac{15x}{30}$ + $\frac{6x}{30}$ + $\frac{10x}{30}$

Add the numerators leaving the denominator

= $\frac{15x+6x+10x}{30}$ = $\frac{31x}{30}$
