Answer 1

I have to refresh quick

Answer 2

we can use the elimination method like last time. but this time, the equations aren't set up to eliminate a variable. we have

y = -x + 2
y = 1/2x - 4

what should we do to the second equation in order to eliminate the x when combining

Answer 3

the first equation, x has a coefficient of -1. to eliminate x, we want x to have a coefficient of 0 after we combine the equations. so our second equation needs to have a coefficient of 1 for x, since -1 + 1 = 0.

so how can we make it so that the 1/2 is made into 1?

Answer 4

I think we have to divide 2 by 1/2 or its the other way around but im gonna go see that other question to see if it helps

Answer 5

you wanna multiply the whole second equation by 2

Answer 6

2(y = 1/2x - 4) is what?

Answer 7

oh and sorry it keeps kicking me out

Answer 8

crap I gtg

Answer 9

alright, good luck :/
