How do I do this math question

9-2c+c= -13

-
9 - 2c + c = -13

1. Combine Like Terms

9 - c=-13

2.Isolate c

-c=-22

c=22

-
Add the variable numbers together and add the regular numbers together
(remember when 9 goes over to -13 it is subtracting from -13 because u must switch the sign of the number when you are making them go to the other side of the equation)

U should get -1c=-22
multiply -1 on both sides
c=22

-
9-9-2c+c=-13-9

-2c+c=-22 add c into -2c will become -c or -1c but you dont put the -1

-c=-22

c=-1/-22

c=22

lol im only in grade 8 but i hope you understand it

-
9 + c -2c = -13
9 - c = -13
add c to both sides
9 - c + c = -13 +c
9 = - 13 + c

add 13 to both sides
13 + 9 = - 13 + c + 13
22 = c

-
9 - c = - 13
22 = c
