5x - 10 = 2
Add 10 to both sides: 5x = 12
Divide both sides by 5: x = 12/5 = 2.4
It is: 16 and 2/3 times 3 = 50
5x10
50000000000
5x10-3 = 0.005 5x10-2 = 0.05 5x10-1 = 0.5 5x100 = 5 5x101 = 50 5x102 = 500 5x103 = 5000 ...
-5x + 2(4x-10)=10
(4x10-1)+(5x10-2)
5x10 = 50 - 4 = 46 Answer - 46
1x10 to the 2 5x10 1x10 to the -1
say 25x10 you take 20x10 200 then 5x10 50 50 plus 200 equals 250
The answer to that equation is 47.
50
It is 50000000.
