@Mehek14 @SkyVoltage

Mehek (mehek14):

solution is where they intersect

Mehek (mehek14):

so write down the number of times they intersect

OpenStudy (anonymous):

only once

Mehek (mehek14):

right

Mehek (mehek14):

and for explanation u can write that because it only intersects once

OpenStudy (anonymous):

is this good ?

Mehek (mehek14):

second one, put x - 1 for y x - 1 = -2x + 8 solve for x and yes that is good

OpenStudy (anonymous):

omg im bad with that

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

x would = 3 ?????????

Mehek (mehek14):

correct :)

Mehek (mehek14):

to find y, put x = 3 y = x - 1 y = 3 - 1

OpenStudy (anonymous):

y = 2

Mehek (mehek14):

so the solution is (3,2)

OpenStudy (anonymous):

is this good ??????????

Mehek (mehek14):

good :) but for the first sentence, put : `substitute y = x -1 for y in the first equation`
