**Introduction to learn how to do elementary algebra:**

**Elementary Algebra** covers all the basic operations and function in algebra topic. The elementary algebra is the main part covered arithmetic. All the basic operation is
presented in this area . This is covering all basic operation of addition multiplication, subtraction, and division. The elementary algebra covers kindergarten level to middle school level. This
is also help to solve for real life problem.

**Write a verbal expression for each algebraic expression:**

**1. 9a ^{2}**

**Answer:**

In this elementary algebra problem we learn how to do the 9a^{2}

Step1: first we take the root for find the factor

Step2: root on the both 9 and a^{2}

Step3: finally we get the answer for 9a^{2}

(3a) ^{2} = **3a * 3a = 9a ^{2}**

**2. 5 ^{2}**

**Answer:**

In this elementary algebra problem we learn how to do 5^{2}

We multiply 5 x 5 finally we get answer for 5^{2}

**25 = 5*5**

**3. 4(xy) ^{2}**

**Answer:**

Step1: first we take the root for find the factor

Step2: root on the both 4 and (xy) ^{2}

Step3: finally we get the answer for 4(xy) ^{2}

** 2xy * 2xy = 4(xy) ^{2}**

**Write an algebraic expression for each verbal expression:**

**1. 15 less than k**

**Answer:**

In this elementary algebra problem we write expression for the given condition

The 15 is less than the variable k value.

**15 < k**

**2. 6 more than twice m**

**Answer:**

In this problem we write expression for the given condition

The value 6 is twice more than the variable m.

**6 > 2m**

**3. 8 increased by three times a number**

**Answer:**

In this problem we write expression for the given condition

The value 8 is increased with the three times of a variable m.

**3n + 8**

**Solving One-Step Equations:**

**1. d - 8 = 17**

**Answer: **

We add 8 on both sides

d- 8+8 = 17+8

** d = 25**

**2. V + 12 = -5**

**Answer: **

**We add -12 on both sides**

V +12 -12 = -5-12

** V = -17**

**3. b - 2 = -11**

**Answer: **

**We add +2 on both sides**

b-2 +2=-11+2

** b = -9**

**4. -16 = m + 71**

**Answer: **

**We add -71 on both sides**

-16-71=m +71 -71

**m = -87.**

**Example: 1**

If x = 6, what is the value of x^{2} + 3x + 7?

**Solution:**

In this problem we learn how to do a given expression x2 + 3x + 7, along with a value for x equal to 6. The correct method is to substitute the numerical value into the expression and then make sure to do the math correctly.

= (6)^{2} + 3(6)+7

= 36 + 18 + 7 = **61 **

**Example: 2**

4x - 5 = 2x – 2 , Solve for x.

**Solution:**

Add +5 = + 5 both sides

4x = 2x + 3

Subtract -2x= -2x both sides

2x = 3

Divide by 2 both sides

2x/2 = 3/2

**X = 3/2.**
