76 + 17x + 9x - 76 = 180 - 76

26x / 26 = 104 / 26

Please show work for full credit! 10^6/ 10^2= 10^3 Why is that false?

noname [10]

10^6/10² = 10³

10^(6 - 2) = 10³

10^4 = 10³

10000 = 1000

this is false because both sides are not equal to each other which is not a solution.

hope this helps, God bless!
