Answer:
a = 8.5
Step-by-step explanation:
The value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.
According to the question,
We have the following equation:
8x = -16
Now, this equation can not be solved using multiplication because 8 is already in multiplication with x on the left hand side. If 8 would have been in division then it could be solved using multiplication.
So, dividing by 8 on both the sides:
x = -16/8
x = -2
Hence, the value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.

Consider the expression 
Use main properties for powers:
1. 
2. 
3. 
Then
The result in scientific notation is 
The result as a decimal is 
-22+(x/35)=-25
add 22 to both sides
x/35=-3
multiply both sides by 35 to cleaf raction
x=-105
number was -105
