Answer:

x = 0, 2

Step-by-step explanation:

{4}^{x}  - 5( {2}^{x} ) + 4 = 0 \\   {({2}^{x})}^{2}    - 5( {2}^{x} ) + 4 = 0 \\  {u}^{2}  - 5u + 4 = 0 \\ (u - 1)(u - 4) = 0 \\ u = 1 \: or \: u = 4 \\  {2}^{x}  = 1 \: or \:  {2}^{x}  = 4 =  {2}^{2}  \\ x = 0 \: or \: x = 2

3y=24 solve by inspection
Ulleksa [173]

Explanation: Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a÷c=b÷c for c≠0

<u><em>First, you divide by 3 both sides of an equation.</em></u>

<u><em>3y/3=24/3</em></u>

<u><em>Then, simplify.</em></u>

<u><em>24/3=8</em></u>

<u><em>8*3=24</em></u>

<u><em>24/8=3</em></u>

<u><em>y=8 is the final answer.</em></u>

<u><em>Hope this helps!</em></u>

<u><em>Thanks!</em></u>

<u><em>Have a great day!</em></u>
