The solution to the given linear equation is x=1
<h3>Solution to linear equation</h3>
Linear equations are equations that has a leading degree of 1.
Given the linear equation as shown below;
8x - 5= 2x + 1
Subtract 2x from both sides
8x - 2x - 5 = 2x + 1-2x
6x - 5 = 1
Add 5 to both sides
6x - 5 + 5 = 5 + 1
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
Hence the solution to the given linear equation is x=1

Answer:
(x+3)(x-5)=(x+3)(x-5)
x^2-2 = x^2-2
Step-by-step explanation:
Answer: Lily is Correct.
Step-by-step explanation:
Lily is correct because the product of 15x52 is 15 times bigger than 15, therefore making a product (way larger) than 15. Lily is correct. Tell me if this helped or didn't help, but I hope it did (: !
Answer:Hint:
the remainder is 2.
Step-by-step explanation:
23≡1 mod 7 and 33≡−1 mod 7.
Edit: The only thing you need from the modular arithmetic is that
a⋅b mod 7=(a mod 7)(b mod 7) mod 7,
meaning the remainder of a product is the remainder of the product of remainders. This is self-evident as a⋅b must have the same remainder as (a−7k)⋅(b−7l).
Since exponentiation is just repeated multiplication, we can write
230⋅320=(23)10⋅(33)6⋅32≡110⋅(−1)6⋅9=9
