Hey there!

$\huge{ \fbox{ \sf{x=9/2 }}}$

$2x+3=12$

To solve, we will need to subtract 4 from both sides.

$2x+3-3=12-3=2x=9\\2x=9$

Now in our second and final step, we will have to divide both sides by 2.

$\frac{2x}{2}=\frac{9}{2} \\\frac{9}{2}\text{(ANSWER)}$

Hope this helps!

Just general definitons:

a TRInomial has 3 terms (tri means three)
a BInomial has 2 terms (bi means two)
a MONOmial has 1 term (mono means one)

the degree is the highest exponent found in the algebraic expression

so they should be pretty easy to solve with that information, but just in case:

1. trinomial, degree of 4
2. binomial, degree of 3
3. monomial, degree of 2

for the final question, all you have to do is plug in 2 for x, so

(2)^2 - 2(2) + 1

4 - 4 + 1

so the answer is 1

Given:

A man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

To find:

The value of the business in Bir.

Solution:

Let x be the value of the business.

It is given that a man owns 3/4 of the share of a business and sells 1/3 of his shares for Bir 10,000.

$x\times \dfrac{3}{4}\times \dfrac{1}{3}=10000$
