Question 1130653: Use elimination to solve the system. (Simplify your answer completely. If the system is dependent, enter a general solution in terms of x and y.)
3(x − 6) = 4y
2(2y + 9) = 3x

3%28x+-+6%29+=+4y
2%282y+%2B+9%29+=+3x
-----------------------
3x+-+18+=+4y
4y+%2B+18+=+3x
---------------------------------
3x+-+4y+=18+
-3x%2B4y=-18++
--------------------------------add
3x+-+4y-3x%2B4y+=18-18+
0=0

which means any x or+y value will satisfy+the system of equations. So there are an infinite number of solutions
So this system is dependent.
