Answer:
x = 11.5
Step-by-step explanation:
Taking the logarithm base 2 will transform this to a linear equation.
2(2x+7) = 3(2x -3)
0 = 3(2x -3) -2(2x +7) . . . . subtract the left side
0 = 2x -23 . . . . . . . . . . . . . simplify
0 = x - 23/2 . . . . . . . . . . . . divide by 2
11.5 = x . . . . . . . . . . . . . . . . add 11.5
The solution is x = 23/2 = 11.5.

This value of x makes the equation become ...
4^(2·23/2 +7) = 8^(2·23/2 -3)
4^30 = 8^20 . . . . . true
Your answer will be the 1st one because it says the distributice property and that is when you multiply a number outside a parenthesis and the number one shows that and also as the right numbers, because 2 fits in 34 seventeen(17) times and 2 fits in 16 eight(8) times, so your answer would be 2(17+8)
Hope this helps
