Algebra 1 help ! please?

Question

Slove the system of equations by any method.

6x - 3y = 3

y = 2x - 1

-6x + 5y = 3

please help ?

xo rosee

god bless you

i dont just want the answer i would like to know how to do it.

Answer 1

You need to eliminate one of the variables.  You can do it by adding two of the equations:

-6x + 5y = 3

+6x - 3y = 3

-----------------------

.         2y = 6 (then divide by 2 to find y)

Once you have the value of y, you substitute that into one of the equations to find x

y = 2x - 1

2x - 1 =...

Alternatively, you can eliminate y by substituting y = 2x -1 into one of the equations:

6x - 3(2x-1) = 3

and solve for x, then substitute this value of x into one of the equations to find y.

Answer 2

plug y=2x-1 in for y in the first equation and solve for x. then, plug the answer for x into the any equation and solve for y. then, plug both variables into the equations and find the answer. hope this helps.

Answer 3

since y=2x-1 you just have to plug it in to the equations

like this...

6x-3(2x-1)=3 or -6x+5(2x-1)=3

then you will find x and plug it into the y=2x-1 to find what y is
