Homework Statement



Solve the following equations using simultaneous equations

Homework Equations



32x[tex]\times[/tex]23y=17

4x[tex]\times[/tex]5y=37

Appologies for the bad equation set-up. The large 'x' is a multiplication sign.


The Attempt at a Solution


My attempt was to divide both of the equations together and then solve for x and y respectively, using the laws of logarithms.
