Answer:
First Question: x = -8
Explanation:
-12x + 4 = 100
firstly we subtract 4 from 4 which will remove it from the equation and then we also subtract 4 from 100.
Now the equation will be -12x=96
Then we divide -12x by -12 to figure out the value of x and we also dive 96 by -12.
-12x/-12= 96/-12
Answer is x = -8
Hopefully that helped :)
