Solve Algebra Word Problems Online

Algebra, which is derived from the Arabic word al–jabr. In Arabic language, ‘al’ means ‘the’ and ‘jabr’ means ‘reunion of broken parts’. The usage of the word algebra can be understood by a simple example. In the equation x + 5 = 9, the left hand side is the addition (sum) of two parts x and 5. If we add (unite) (–5) to each side of the equation, we get

(x + 5) + (–5) = 9 + (–5) or x + [5 + (–5)] = 9 – 5 or x + 0 = 4 or x = 4.

Here 9 and -5 are reunited to get 4. This type of mathematics is called algebra.

Problem 1:


The sum of twice a number plus 13 is 75.  Find the number.

Solution:

Given : The sum of twice a number and 13 equals 75.

By using the numbers and a variable that represents something, N in the case (for number),

You can write the equation with the given problem

2N + 13 = 75

By solving the equation we can get the value for variable

2N + 13 = 75     Equation.

- 13 = -13     Add (-13) to both sides.

______________

2N      =  62

N       =  31     Divided both sides by 2.

So, the answer is N= 31

Understanding What is Prism is always challenging for me but thanks to all math help websites to help me out.

Problem 2:


The number which is decreased by 24 is 5 times its opposite. find number.

Solution:

opposite means negative.By the given question we can make an equation and it describes the problem

N - 24 = 5(-N)        Equation.

N - 24 = -5N          Multiplied out.

5N + 24    5N + 24     Add (5N + 24) to

_______________________     both sides.

6N      =       24

N = 4            Divide both sides

by 6 to isolate N

So the answer is N= 4
