Answer:

Simplifying

2x + -10y = 15

Solving

2x + -10y = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10y' to each side of the equation.

2x + -10y + 10y = 15 + 10y

Combine like terms: -10y + 10y = 0

2x + 0 = 15 + 10y

2x = 15 + 10y

Divide each side by '2'.

x = 7.5 + 5y

Simplifying

x = 7.5 + 5yStep-by-step explanation:

The correct answer is option D

The solution is shown below:

$x^{2} +16 \\ \\ 
= x^{2} +(4)^{2} \\ \\ 
= x^{2} -(-1)(4)^{2} \\ \\ 
= x^{2} -i^{2} (4)^{2} \\ \\ 
= x^{2} -(4i)^{2} \\ \\ 
=(x+4i)(x-4i)
