5th Grade Math Variables

Introduction to 5th grade math variables:

In mathematics, 5th grade math variables are using addition and subtraction operation with variables. Single-symbol are called for variables are the normal, with x, y, and z being most common using in variables problem. Constants are generally denoted as a, b, c. In mathematics, constants and variables are usually set in an italic typeface.

Specific branches and applications of mathematics regularly have specific naming conventions for variables.

Meanings or variables with similar roles are regularly assigned consecutive letters. For example, x, y, and z is the three axes in 3D coordinates space are conventionally.

Examples problems for 5th grade math variables:


1. Find the x value, for the given for single variable expressions.

18x + 2 = 38

Solution:

18x + 2 = 38

Subtract (2) with both sides,

18x + 2 – 2 = 38 – 2

18x = 36

Divide (18) with both sides,

18x / 18 = 36 / 18

x = 2.

The solution to the given expression in single variable x = 2.

2. Find the y value, for the given for single variable expressions.

4y + 4 = 20

Solution:

4y + 4 = 20

Subtract (4) with both sides,

4y + 4 – 4 = 20 – 4

4y = 16

Divide (4) with both sides,

4y / 4 = 16 / 4

y = 4.

The solution to the given expression in single variable y = 4.

3. Find the z value, for the given for single variable expressions.

5z + 5 = 30

Solution:

5z + 5 = 30

Subtract (5) with both sides,

5z + 5 – 5 = 30 – 5

5z = 25

Divide (5) with both sides,

5z / 5 = 25 / 5

z = 5.

The solution to the given expression in single variable z = 5.

4. Find the x value, for the given for single variable expressions.

6x - 2 = -38

Solution:

6x - 2 = -38

Add (2) with both sides,

6x - 2 + 2 = -38 + 2

6x = -36

Divide (6) with both sides,

6x / 6 = -36 / 6

x = -6.

The solution to the given expression in single variable x = -6.
