<h2> Answer-:</h2>
There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160
or
25x+10y=160
there are different combinations of the two so im not sure T_T
<h2> The End</h2>
I believe your answer is (3) -9.
You use the first equation listed since x<0
So 2(-5)+1=-10+1=-9.
