Answer:

Step-by-step explanation:
4 x 10^7 is 40000000
4 x 10^3 is 4000
We are told that 4x10^7 is something times as much as 4x10^3
So we will work backwards to find the answer,
If you divide 40000000 by 4000 you will get 10000
10000 is the same as 10^4
Answer:
x = 2, x = -5/2
Step-by-step explanation:

2x = -5
x = -5/2
x - 2 = 0
x = 2
