Introduction for pre algebra final exam:

Algebra is an important chapter in mathematics.  Pre algebra is the fundamentals basic concept of algebra chapter which helps in upbringing school students minds.It includes the concepts of addition, subtraction, multiplication, division, decimal, fraction, shapes, and so on.  In this content, we will study about some problems in pre-algebra. I like to share this How to Solve Binomials with you all through my article.

Example Problems - Pre Algebra Final Exam

Example 1 problems - Pre algebra final exam

Find out the values of x, for the given equation x + 20 = 30.

Solution:

The given equation is x + 20 = 30

Now, we need to subtract the values of 20 on left hand and right hand sides,

x + 20 – 20 = 30 – 20

x + 0 = 10

x = 10

The value of x is 10

Answer:  10

Example 2 problems - Pre algebra final exam

Find out the values of x, for the algebraic equation is x - 6= 15.

Solution:

The given equation is x – 6 = 15.

Now, we are going to add the values 6 on both left hand and right hand sides

x – 6 + 6 = 15 + 6

x – 0 = 21

x = 21

The value of x is 21

Answer:  21

Example 3 problems - Pre algebra final exam

Find out the values of x, for the algebraic equation is `2x / 6` = 4.

Solution:

The given expression is `2x/6` = 4

Now, we are going to multiply the values 6 on both left and right hand side,

`2x/6` `xx` 6 = 4 `xx` 6

2x = 24

Here, we need to divide 2 on both sides

`2x/2 = 24/2`

x = 12

Answer:  12
