Answer: 764
Step-by-step explanation:
There are a couple of sets of numbers that would add up to -294. Obviously -293 and -1, but I am sure your teacher wouldn't be to happy with that answer :D. A better answer could be -147 and -174; or maybe different numbers like -156 and -138.
I hope this helps!
You would add the like terms by changing them over the equals sign
6r+18=-26+6r
subtract 6r from both sides
18=-26
which is false
