Hector needs 64 liters of 25% and 96 liters of 50% sulfuric acid as per linear equation.

A linear equation is a equation that has a variable or variables with highest degree of 1.

Given, the total amount of solution is 160 liters.

Total solution should have 40% sulfuric acid.

Hector has 25% and 50% sulfuric acid solutions respectively.

Let, he took x and (160 - x) liters of each solution respectively.

Therefore, x × 0.25 + (160 - x) × 0.5 = 160 × 0.4

⇒ 0.25x + 80 - 0.5x = 64

⇒ 0.25x = 16

⇒ x = 64

Therefore, he needs 64 liters and (160 - 64) liters = 96 liters of solutions with given percentage of sulfuric acid respectively.
