• Algebra -

a.
Let x = amount of 10% salt solution in gallons
Since the total volume must be equal to 5,
Let 5-x = amount of 25% salt solution in gallons

We'll do a salt balance here. Thus, the equation would be,
0.1x + 0.25(5-x) = 0.2(5)

b.
Solving,
0.1x + 0.25(5-x) = 0.2(5)
0.1x + 1.25 - 0.25x = 1
-0.15x = 1 - 1.25
-0.15x = -0.25
x = 1.67 gallons (10% solution)
5-x = 3.33 gallons (25% solution)

Hope this helps :3
