How do I find the point of intersection for the pair of Iines?
A). First replace y in the first equation by the right hand side of the second equation:
4x - 1 = 2x + 3
subtract 2x from both sides: 2x - 1 = 3
add 1 to both sides: 2x = 4
divide both sides by 2: x = 2
put this into the first equation: y = 2*2 + 3 or y = 7
hence the point of intersection is (2, 7)
B) You have only supplied one equation
C) Try using the same approach I used in A) above.
