How to solve problems that can be represented by: a system of two linear equations.

2x + 5y = 26
4x - 3y = 32

The water pressure on a swimmer's ears varies directly with the depth of the pool. If the pressure is 4.5 pounds per square inch at a depth of 10 feet, what will the pressure be at a depth of 12 feet?
