OpenStudy (kaloemalia):

@triciaal Please help me!

iYuko (iyuko):

Graph it. Where the 2 line intercept thats your answer.

OpenStudy (michele_laino):

we can apply the elimination method, so we get: \[\Large \frac{3}{2}x = - \frac{x}{2} + 4\]

OpenStudy (michele_laino):

please solve that equation for x

OpenStudy (kaloemalia):

how do i do that ?

OpenStudy (kaloemalia):

I'm sorry, im lost!

OpenStudy (kaloemalia):

hello?

OpenStudy (michele_laino):

If I multiply both sides by 2, I get: \[3x = - x + 8\]

OpenStudy (michele_laino):

what is x?

OpenStudy (kaloemalia):

-5?

OpenStudy (michele_laino):

we have to add x to both sides, first, thenwe can write: \[4x = 8\] now, please, divide both sides by 4, what do you get?

OpenStudy (kaloemalia):

1,2

OpenStudy (kaloemalia):

1 and 2

OpenStudy (michele_laino):

x=2

OpenStudy (michele_laino):

since 8/4=2
