Answer 1

Hi there!

I believe your answer is:

D. infinite number of solutions

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

`\boxed{\text{Calculating the Answer...}}\\\\\left \{ {{8x + 4y = 20} \atop {-10x - 5y = -25}} \right.\\-----------\\5(8x + 4y = 20)\\4(-10x - 5y = -25)\\\\40x+ 20y = 100\\\-40x-20y=-100\\\\\boxed{0 = 0}`

⸻⸻⸻⸻

There are an infinite number of solutions.
