Answer:
x = -7
Step-by-step explanation:
Given:
5 – x = 12
Subtract 5 from both sides
5 – x - 5 = 12 - 5
- x = 7
Note: the coefficient of -x is -1
- x = 7
Divide both sides by the coefficient of -x
- x / -1 = 7 / -1
x = -7
Check
5 – x = 12
5 - (-7) = 12
5 + 7 = 12
It is possible to subtract a number from 5 and have more than 5 as your answer when the unknown number is a negative value

Answer:
99 yeah yeah
Step-by-step explanation:
okayyyyyyy
You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
