Answer 1

\(\sf\Huge\color{green}{Welcome~to~OpenStudy~♥}\)
Now lets begin do you know how to start off solving this?

Answer 2

no

Answer 3

Ok do you know how to change this into y intercept form?

Answer 4

y=mx+b

Answer 5

DING DING DING :)

Answer 6

So we have these two equations that we need to change to y intercept form \[2x+7y=-14 \]
and

\[4x-3y=-19\]

Do you know how to change those into y intercept form?

Answer 7

why are you changing them to y intercept form ?

Answer 8

Because then that way you can put it in a graphing calculator and see where the two lines intersect and get your ordered pair. Would that be right?

Answer 9

or you could just solve by elimination

Answer 10

I suppose you could do it your way...but that is not really teaching them to solve it by theirselves

Answer 11

True true, but everyone is different no worries though. |^_^|
