How unspecific? What's the cost of one
Answer: One solution
Step-by-step explanation:
Given
-5x-8=8
Add 8 on both sides
-5x-8+8=8+8
-5x=16
Divide -5 on both sides
-5x/-5=16/-5
x=-3.2
Therefore, it has one solution
Hope this helps!! :)

I will solve your system by substitution.<span><span>x=<span>−2</span></span>;<span>y=<span><span><span>23</span>x</span>+3</span></span></span>Step: Solve<span>x=<span>−2</span></span>for x:Step: Substitute<span>−2</span>forxin<span><span>y=<span><span><span>23</span>x</span>+3</span></span>:</span><span>y=<span><span><span>23</span>x</span>+3</span></span><span>y=<span><span><span>23</span><span>(<span>−2</span>)</span></span>+3</span></span><span>y=<span>53</span></span>(Simplify both sides of the equation)
Answer:<span><span>x=<span>−<span><span>2<span> and </span></span>y</span></span></span>=<span>5/3
<span>
so the answer is B (the second choice)
