This equation -r + 6 + 8r - 14

7r-8

yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14

Firstly we will solve -1r +8r

+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r

Now we move on to +6-14

this is just simple addition and subtraction

what is 14-6 it is -8

-14 overpower 6 so we use its sign

Lastly we put it all together and get

7r - 6
