Question 5254: how do you get the x and y varibles in this problem
4x - 3y = 12
x + 2y = 14

You can put this solution on YOUR website!
4x - 3y = 12
x + 2y = 14


Multiplying eqn1 by 2 and eqn2 by 3 we get,
8x - 6y = 24
3x + 6y = 42


Adding the two eqns we get
11x=66
x=6


from eqn2 we get,2y=14-x,y=(14-x)/2
y=(14-6)/2=8/2=4


hence,
x=6,y=4


Hope this helps,
good luck.
