Simple Solution Math Book

Introduction for simple solution mathematics book:

Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions.  The mathematician Benjamin Peirce called mathematics "the science that draws necessary conclusions". Arithmetic operations and numbers are mainly used in mathematics. Let us see some simple solution math book.  (Source: Wikipedia)



Example Problems for Simple Math Book:

Let us see some simple math book here:

Problem 1:

Solve the equation 2x - 24 = 78

Solution:

Given equation 2x - 24= 78

Add 24 on both the sides of the equation, we get

2x = 102

Divide the obtained equation by 2 on both the sides, we get

x = `102 / 2` = 51

Therefore the final answer for this equation is x =51

Problem 2:

Solve:

Given function `(x / 4)` = 14

Solution:

Given, `(x / 4)` = 14

Multiply the above equation by 4 on both the sides, we get

x = 14 * 4

x = 56

Therefore the final answer is x = 56

Problem 3:

Divide 75 by 5

Solution:

Given, 75 divided by 5

It can be written as,

75 ÷ 5

Divide the value of 75 by 5, we get

75 ÷ 5 = 15

Therefore the final answer for the division is 15

Problem 4:

Add this two equations x - y2 + 4 and x2 + 2x + y2 - 22

Solution:

The given equations are, x - y2 + 4 and x2 + 2x + y2 - 22

Now we have add the two equations, we get

= x - y2 + 4 + x2 + 2x + y2 - 22

= x2 + 3x - 18

Therefore the final equation will be x2 + 3x - 18

Problem 5:

Subtract the two equations (x - 2y + 18) and (3x + 8y + 60)

Solution:

Given equations are (x - 2y + 18) and (3x + 8y + 60)

Subtract the two equations, we get

= (x - 2y + 18) - (3x + 8y + 60)

Expand the above equation, we get

= x - 2y + 18 - 3x - 8y - 60

= - 2x - 10y - 42

Divide the obtained equation by - 2, we get

= x + 5y + 21

Therefore the final answer is x + 5y + 21



Practice Problems for Simple Math Book:

Problem 1:

Solve x + 24 = 3x - 38

Solution:

Therefore x = 31

Problem 2:

Solve x2 - 144 = 0

Solution:

Therefore x = ± 12

Problem 3:

x + y = 23, find the value of x at y = 2

Solution:

Therefore x = 21
