Y=_x+4<br> x + 2y =<br> 8<br> How many solutions dose this linear system have
jeyben [28]

Answer:

X=-1, y=4

Step-by-step explanation:

y = x + 4 \\ x + 2y = 8 \\  =  =  =  =  =  =  =  =  =  =  =  = \\ y - x = 4 \\ x + 2y = 8

by using eliminating property

3y = 12 \\ y = \frac{12}{3}    = 4

by substitution

X=-1

For 7/8 x 2/3 = the answer in simplest form, so we do the repricoral?
stiks02 [169]
Hello, so a simple way to do it is to cross cancel and then you would end up with 7/4 x 1/3 and it would equal 7/12 and that’s in simplest form.

How do I do GCF (greatest common factor on -5y - 35? I need help because I am not good at it.
ICE Princess25 [194]

Answer:

-5(y+7)

Step-by-step explanation:

Well, the numbers you can divide 5 with are 1 and 5.

35 divides both with 1 and 5 too, but since 5 is the greatest, you choose 5.

so,

you divide both with -5, since both are negative.

-5y/-5 = y

-35/-5 = 7

so,

-5(y+7)

check:

-5*y = -5y

-5*7 = -35

so,

-5y-35, that's true.
