use cramer's rule to solve the given system:
2x+4y=14
4x+3y=18
First find the determinant:
2 4
4 3



1/d=-1/10
Now replace the x's with the answers. Do the same thing we did to find the determinant and multiply the answer by 1/d=-1/10
14 4
18 3





Now replace the y's with the answers and do the same thing you did to get the x.
2 14
4 18





The solutiong is: (x,y)=(3,2)
Happy Calculating!!!
