Pre algebra home work
Introduction:
Math Pre algebra is the basics of algebra. Pre algebra consists of single variables equations and numbers. All the pre algebra problems are one step or two equations solving only. These problems involve basic arithmetic operations only. Those operations are addition, subtraction, multiplication and division. In online, many websites offers home work help in pre algebra topic. Through online, students can get more help at less cost. Moreover, home work help in online is very interactive and fun. In this article, we are going to see about pre algebra home work help.
Pre algebra home work help examples:
Pre algebra home work help example 1:
Solve the equation; x + 10 = 15
Solution:
X + 10 = 15
Subtract 10 on both sides,
X + 10 – 10 = 15 – 10
X = 5
The answer is 5.
Pre algebra home work help example 2:
Solve the equation; x – 5 = 20
Solution:
X – 5 = 20
Add 5 on both sides,
X – 5 + 5 = 20 + 5
X = 25
The answer is 25.
Pre algebra home work help example 3:
Solve the equation; 2x/3 = 8
Solution:
2x/3 = 8
Cross multiply 3 with 8,
2x = 8*3
2x = 24
Divide 2 on both sides,
2x/2 = 24/2
x = 12
The answer is 12.
Pre algebra home work help example 4:
Solve the equation; 2 1/10x = 1 1/6
Solution:
2 1/10x = 1 1/6
Here, convert mixed number to improper fraction,
2 1/10 = (2*10) + 1/10
= (20 + 1)/10
= 21/10
1 1/6 = (1*6) + 1/6
= (6 + 1)/6
= 7/6
21x/10 = 7/6
Inverse the number 21/10 and move to opposite side,
X = 7/6 * 10/21
X = 70/126
Simplify the expression,
X = 35/63
The answer is 35/63.

Pre algebra home work help example 5:
Solve the expression; 10x + 36 = 38x – 47
Solution:
10x + 36 = 38x – 47
Subtract 10x on both sides,
10x + 36 – 10x = 38x – 47 – 10x
36 = 28x – 47
Add 47 on both sides,
36 + 47 = 28x
28x = 83
Divide 28 on both sides,
28x/28 = 83/28
X = 2.96
The answer is 2.96.
Pre algebra home work help example 6:
Solve the inequality: 2x + 2 > 8
Solution:
2x + 2 > 8
Subtract 2 on both sides,
2x + 2 – 2 > 8 – 2
2x > 6
Divide 2 on both sides,
2x/2 > 6/2
x > 3
The answer is x > 3.
