Whoever finds the asnser first gets a medal!

mathmate · Answer

You have not given the choices. 
It is easier with the choices because we don't need to solve the equations.

anonymous · Answer

divide second equation by 5 
$$\Large y= \frac{x-28}{5}$$

anonymous · Answer

put the above value in the first equation for y
$$\Large 3x-4(\frac{x-28}{5})=18$$
simplify this and solve for x
