64 = 2 ^6
16 = 2^4 =
2^ 6*(2x+4) = 2^4 * 5x
6(2x+4) = 20x
10/3 x = 2x +4
4/3 x = 4
x = 3
you can also use logarithms like so
(2x+4)ln64 = 5x ln16
ln64/ln16 = 3/2
3/2 * 2x + 3/2 * 4 = 5x
3x + 6 = 5x
2x = 6
x = 3
We know that 2x+7 = 27, so that means that
if 2x+7 = 3x+1 then
3x+1 = 27 also
but we are told that 3x+1 = 28, so that means that
2x+7 does not equal 3x+1
