C1 Maths: Line Intersection?Watch

#1

Hey

I am having trouble with the following question about line intersections

It is from the C1 January 2009 AQA Maths Paper

The question is:

Line AB has the equation 3x + 3y = 8
The point A has the coordinates (6,-2)

The line AB intersects the line with the equation 2x + 3y = 3 at point B

Find the coordinates of B?

Any help would be appreciated! thanks x

Solve the equations of the lines simultaneously.

Line AB has the equation 3x + 3y = 8
I think there is an error in the question.

If you use 3x+5y = 8 for the line AB, it should all work out.

oops yeah its supposed to be 3x + 5y = 8

how do you work it out though?

As previously stated, you need to solve the two simultaneous equations. If you don't know how, have a look in your textbook, if you do, and it's not working out, then post some working.
