Algebra is one of a part of arithmetic that uses letters in place of some unknown numbers. It is concerning about learn the rules of operations and dealings, and the constructions. It also was including the conditions, polynomial expressions, equations and algebraic arrangement. In other words, we use numerals like 1, 2, 3, etc to represent numbers. In algebra we use numbers as well as letters of the alphabet such as a, b, c, etc for any numerical values we choose. In this article we shall discuss about algebra test questions.First we will solve some sample questions for algebra test and then do some practice questions.
Sample Questions for Algebra Test :
Ex 1: Solve the linear questions
19x - 7 = 21x – 9
Solution: Subtract 21 x from both sides of the above equation, we get the below term
-2x – 7 = -9
Add 7 to both sides of the above equation, we get the below term
-2x – 7 + 7 = - 9 + 7
-2x = - 2
Divide both sides by -2 of the equation, we get
X = 1
The answer is x = 1
Test the answer for the given equation. Replace with in the above given equation for x. If the left side of the equation sum value is equal to the right side of the equation sum value after the replacement of x value, you have got the exact answer.
Left side of the equation:
19(1) - 7 = 12
Right side of the equation:
21(1) - 9 = 12
Ex 2: Solve the given Questions
12− (3x + 7) = 2x
Solution: In the given equation is expanding and the terms are out the bracket.
12 − (3x + 7) = 2x
12 −3 x − 7 = 2x
(12 – 7) − 3x = 2x
5 – 3x = 2x
Now we are identify that it is easier to get all the x value on the right side of the given equation, by adding x to both sides of the above equation.
5 = 5x
Now we divide both sides by 5 and swap the sides:
We get the x value is 1
Test the answer for the given equation. Replace with in the above given equation for x.
We get
12 – 3(1) + 7 = 2(1)
12 – 3 - 7 = 2
Practice Questions for Algebra Test :
Solve 17 x - 6 = 23 x – 18
Ans: x = 2
Solve 13− (5x + 9) = -3x
Ans: x = 2
