Answer:
<h2>x = 1 - 4i or x = 1 + 4i</h2>
Step-by-step explanation:
We are given that:
5[2p-4(p+5)]=25
<span>
First thing to do is to divide everything by 5 so that:</span>
2p-4(p+5)=5
Then distribute -4:
2p – 4p – 20 = 5
Combine like terms:
-2p = 5 + 20
-2p = 25
<span>p = -12.5</span>
You are in debt for 15$, and someone pays it off by 10$. How deep are you now
Answer: {±2√3}
Step-by-step explanation: Since only one term contains an x in this problem, we can simply get the x by itself by dividing both sides by 5 and then square rooting both sides to get x = ±√12
Remember to use plus or minus when
square rooting both sides of an equation.
Now, √12 breaks down to 2√3 so our
final answer is {±2√3}.
If the variable only appears in one of the terms in the equation,
you can solve it by simply isolating the variable.
