Question

2. Consider an alloy A? made of gold and silver in which the mass ratio of gold to silver is 2:3, and another one A? with the mass ratio 3:7. You need to create 8 kg of a new alloy A? with the mass ratio 5:11. How many kilograms of A? and A? do you have to mix? Solve the problem by creating and solving a SLE.

Consider an alloy A_(1) made of gold and silver in which the mass ratio of gold to silver is 2:3, and another one A_(2) with the mass ratio 3:7. You need to create 8kg of a new alloy A_(3) with the mass ratio 5:11. How many kilograms of A_(1) and A_(2) do you have to mix? Solve the problem by creating and solving a SLE. 2.
