Answer 1

what do you need help with?

Answer 2

ummm

Answer 3

?...

Answer 4

Use the Substitution Method to solve the following system of equations.
2x - 9y = 1
x - 4y = 1

Answer 5

okay for the first equation get either the y or the x on one side. its your choice

Answer 6

so which do you wanna move on to the other side? the x or the y?

Answer 7

x

Answer 8

okay so lets do the x-4y=1 equation. subtract x from both sides and subtract one from both sides. you'll get
-1-4y=-x
divide both sides by negative 1 and you'll get
1+4y=x
now you have x so plug x back into the first equation.

Answer 9

THE ANSWERS ARE
(1, 5)

(-5, -1)

(5, 1)

(-5, 1)

Answer 10

we're getting to it.

Answer 11

HAHA

Answer 12

OK

Answer 13

when you plug x back into the second equation, 2(1+4y)-9y=1 and solve

Answer 14

you should come up with 2+8y-9y=1
combine like terms you'll get
2-y=1
subtract one and add y to both sides to get
2-1=y
so y=1
plug y back into the original bottom equation.

Answer 15

x-4(1)=1 multiply
x-4=1 add 4 to both sides
x=5
so your answer is..?
