ranga · Answer

Which is considered the first equation and which is the second?

anonymous · Answer

the system of equations the picture down there is one equation and the second equation in the question they are both tied together

ranga · Answer

Yes, I understand that.  But the answer makes reference to the "first" equation and the "second" equation.  You have typed one equation and you have a link for another.  I am asking which is the "first" equation and which is the "second" equation as it appears in your book?

anonymous · Answer

first equation is the picture the second is in the question itself

ranga · Answer

y = 3/4x + 3     (1)
2x – 4y = 6        (2)

To use elimination, you have to write the first equation in the standard form.

ranga · Answer

Equation (2) is already in the standard form.  But equation (1) is in the slope-intercept form.  Rewrite equation (1) in standard form before using the elimination method to solve the equations.
