What is the solution to the system of equations?

OpenStudy (neonumbrella5115):

The link has one equation, which you cannot solve as the directions imply.

OpenStudy (tileer139):

thats not it hold on

OpenStudy (tileer139):

x=3y+5 x-4y=3

OpenStudy (tileer139):

thats it

OpenStudy (tileer139):

i will medal

Mehek (mehek14):

plug 3y + 5 for x in the second equation

OpenStudy (tileer139):

i dont know how to do that

Mehek (mehek14):

instead of x, put 3y + 5 3y + 5 - 4y = 3

OpenStudy (tileer139):

i still dont know how to solve it

Mehek (mehek14):

3y - 4y = ?

OpenStudy (tileer139):

-1

OpenStudy (tileer139):

y

Mehek (mehek14):

5 - y = 3 solve for y

OpenStudy (tileer139):

do i have to plug in 3y+ 5

Mehek (mehek14):

we already passed that step

OpenStudy (tileer139):

so it would be 8

Mehek (mehek14):

3 - 5 = ?

OpenStudy (tileer139):

i thaouht u had to do the opposite

Mehek (mehek14):

opposite of +5 is -5 3 - 5 = ?

OpenStudy (tileer139):

-2

Mehek (mehek14):

-y = -2 y = 2

OpenStudy (tileer139):

so wat r the cordinates

Mehek (mehek14):

(11,2)

Mehek (mehek14):

plug 2 for y in any equation

OpenStudy (tileer139):

thanks u get a medal
