Question: Set up systems of equations and solve by any appropriate method. All numbers are accurate to at least two significant digits. In a laboratory, electrolysis

Set up systems of equations and solve by any appropriate method. All numbers are accurate to at least two significant digits.

In a laboratory, electrolysis was used on a solution of sulfuric acid, silver nitrate, and cupric sulfate, releasing hydrogen gas, silver, and copper. A total mass of 1.750 g is released. The mass of silver deposited is 3.40 times the mass of copper deposited, and the mass of copper and 70.0 times the mass of hydrogen combined equals the mass of silver deposited less 0.037 g. How much of each is released?
