Answer:
Let x be the unknown quantity of 50% silver.
Look at the silver concentrations... This will be 0.5x of actual silver,
Added to 5% silver in 500g or 0.05(500)g of actual silver
Totaling to (500+x)g of 20% silver which will have 0.2(500+x)g of silver
Your equation is:
0.5x + 0.05(500) = 0.2(500+x)
Solve for x to find the grams of 50% silver used
