Question

Take the deepest dive of an elephant seal and add it to the deepest seawater scuba dive by diver John Bennet. The result is 6,024 ft. Two times the elephant seal's depth minus Bennet's depth is 9,024 ft.

Answer 1

`x = 5016`

`y = 1008`

Explanation:

Given

Let:

`x \to Elephant\ seal`

`y \to Bennet`

From the first statement, we have:

`x + y = 6024`

From the second, we have:

`2x - y = 9024`

Required

Find x and y

Add both equations to eliminate y

`x +2x + y - y = 6024 + 9024`

`3x = 15048`

Divide both sides by 3

`x = 15048/3`

`x = 5016`

Substitute
`x = 5016` in
`x + y = 6024`

`5016 + y = 6024`

Solve for y

`y = 6024 - 5016`

`y = 1008`
