Answer: Divide each side by 5
Explanation:
Let's say we replaced the expression (2^x+4) with the variable w
That gives the simplified equation of 5w = 15. To solve for w, divide both sides by 5. This will undo the multiplication of 5 on w.
5w = 15
5w/5 = 15/5
w = 3
Once w is isolated, we'll replace w with 2^x+4. So,
2^x+4 = 3
In short, 5(2^x+4) = 15 becomes 2^x+4 = 3 after dividing both sides by 5.
