Answer:
<u>x = 7</u>
Explanation:
Because 25 is a perfect square of 5, we can turn
=
into
=
Since the bases are now both equal, we can completely ignore them, as we are only trying to find x. This leaves us with:
3x - 5 = 2x + 2
All we have to do now is solve for x:
x - 5 = 2 <em>Subtract 2x from both sides.</em>
<u>x = 7</u> <em>Add 5 to both sides.</em>
