Respuesta :
-7x - 9 = - 93
move -9 to the other side
sign changes from -9 to +9
-7x-9+9= -93+9
-7x= -93+9
-7x= -84
divide both sides by -7 to get x by itself
to get +x
-7x/7= -84/-7
answer:
x= 12
Answer:
X=12
Step-by-step explanation:
According to the way I learned it, you would add 9 since you are subtracting it and since it is subtracted, it would be considered a negative number so it would cancel out if you add 9. You would also add 9 to -93 which would give you -84. Bring it down and it will become -7x=-84. Divide both sides by -7, canceling out -7, and -84 divided by -7 is 12. Since they are both negative, you make it positive according to integer rules and therefore, x=12.
