We can solve for x by equating the exponents in the equation 7^(4x + 10) = 7^(2x). This gives us 4x + 10 = 2x. Solving for x, we get x = 5/2.

Therefore, x = 5/2.

You were close, guest, but when you solve for x, x=-5.

4x+10=2x

-2x.     -2x

2x+10=0

     -10 -10

2x=-10

/2.    /2

x=-10/2

x=-

But your first steps were correct, so kudos to that!
