Basic algebra test prep
Introduction :
Basic Algebra covers the all basic operations and function in this topic. The elementary algebra is the main part in the arithmetic .all the basic operation is presented in this area. This is includes all fundamental operation of addition multiplication, subtraction, and division. The basic algebra covers kindergarten level to middle school level. This is help to solve for real life problem.
Basic algebra test prep problems
Here we will learn some basic algebra test prep examples
Ex: 1
If x = 6, what is the value of x2 + 3x + 7?
Sol:
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
Ex: 2
(−13a +5b)+(18a +(−18b))
Sol:
= −13a +18a +5b +(−18b)
= 5a +(−13b)
= 5a −13b
+By the commutative law, we may also write this as −13b +6a.
Basic algebra test prep problems for practice
Here we will see problems on algebra test prep problem
Q: 1
Find the value of X [1 + (x + 1)1/2]2 at x=3.
Putting x = 3 in x [1 + (x + 1)1/2 ]2 becomes
3[1 + (1 + 3)1/2]2
= 3[1 + 41/2]2
= 3[1 + 2]2 = 3[3]2
= 3(9)
= 27
Q: 2
The sum of three times a number and three is six. Find the number
Sol:
Let x be the number.
The sum of 3 times the number x and 3 is 3x + 3 and ‘is 6’ translated to ‘equal to 6’ i.e. 3x + 3 = 6
3x +3 = 6
3 x = 3
x=1
Q: 3
Solve for x: 7x- 5=79
Sol
7x= 79+5
7x=84
x=12
Q :4
Solving inequalities in algebra
Solve: │4x – 4 │ = 8
Sol:
Use the result, if |x| = a, then x = a or x = -a
Here │4x – 4 │ = 8
So, it has either 4x – 4 = 8 or 4x – 4 = -8 values.
Answer every equation by the addition and multiplication principles.
4x = 12 , 4x = -4
After solving the equation, we get
Answer x = 3 , x = -1.
