Use the solution of the system below to find xy:
4x2y=11
3x4y=6
a 11.3
b 0.1
c 0.1
d 11.3
please explain how to do this.
Thanks!!!

multiply the 1st equation by 2 and then add them to get rid of the y's [and hence find the x]
once you have the value of x sub it into either of the two equations to find y.
then just do xy
Hope that helps
