**Jai**, Friday, October 28, 2011 at 3:21amadd the two equations to get y alone:

y = -3/4x + 1/4

y = 3/4x - 3/4

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

2y = -2/4

y = -1/4

then substitute this value of y to either of the equations and solve for x. in this case let's substitute this to the first give equation:

y = -3/4x + 1/4

-1/4 = -3/4x + 1/4

-1/4 - 1/4 = -3/4x

(-2/4 = -3/4x)*4

-2 = -3x

x = 2/3

hope this helps~ :)
