Please answer in manner like
let .... be x
let .... be y
please answer Answer by josgarithmetic(39617) (Show Source):
Performing the left-side multiplications will give an xy number on the left sides; and because when you subtract xy from left and right sides on both equations, the xy number is eliminated. You obtain the system:
and
Reform as the equivalent system: AND . Subtract first equation from second equation and obtain ... and pick either equation to find y.
