Answer 3

(6,-2)

Answer 4

multiply the second equation by \(-2\) and then add

Answer 5

at this point you can almost do it in your head i bet

Answer 6

I think it's cause I am rushing now to go to work lol

Answer 7

go slow, i know you got this

Answer 8

3x + 4y = 10
x + 2y = -2

form 2nd equation x = -2-2y

now plug this into first equation:

3(-2-2y) + 4y = 10
-6 -6y + 4y = 10
-2y = 16

can you continue?

Answer 9

So if it's the same line it's infinitie

Answer 10

you're killing me

Answer 11

\(\large \begin{array}{llll}
3x+4y=10&&\quad \cancel{3x}+4y=10\\
x+2y=-2&{\color{red}{ \times -3}}\implies &\cancel{-3x}-6y=6\\
\hline\\
&&\qquad \qquad \square =\square
\end{array}\)

Answer 12

Lol I was asking for a different one with that @satellite73

Answer 13

\[3x + 4y = 10\\ x + 2y = -2 \]\[3x+4y=10\\-2x-4y=4\]

Answer 14

oh - deosn't it ask for substitution method for this one?

Answer 15

hmmm oh ... yeah =(

Answer 16

can u continue with i left off vshiroky?

Answer 17

*where

Answer 18

if -2y = 16
what is y?
