3x + 2y + -2x + 8y pls help
raketka [301]
<h2>Answer:</h2>

x+10y

<h3>Step-by-step explanation:</h3>

3x+2y+(-2x)+8y

First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + &amp; - equals to -(minus) :-

3x-2x+2y+8y= x+10y

I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.
