How to simplify the expression by combining like terms

-r+6+8r-14
-r     -r
6+7r-14
+6     +6
7r-8

It is 7r-8 because you combine like terms

-r + 6+8r-14
You subtract r to 8r which is 7r

So now it is 7r + 6 - 14

Then you add 6 to -14 which is -8

And you get 7r -8

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph

What am i doing here. add?
