Answer 1

If we know that 180-5=128 that means that that equation must be equal to 128.

(2^3x+1)=128

By putting 128 into exponential form with a base of 2 you get 2^7:

(2^3x+1)=2^7

Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:

3x=6 to 3/3x = 6/2

This gives us a final answer of:

x=2
