Example problems for learn online algebra expressions help:
1. Write algebra expressions for given sentence;
Twice a number, increased by eight, is twenty-four.
Solution:
Given the twice a number, increased by eight, is twenty-four,
Let as the number be a, then we get,
2a + 8 = 24
Add -8 on both sides, then we get,
2a + 8 - 8 = 24 - 8
2a = 16
Both sides divided by 2, then we get,
`(2a)/2 = 16/2`
`a = 8`
Answer:
Algebra expression for this problem is 2a + 8 = 24
Simplified algebra expression is a = 8.
2. Write algebra expressions for given sentence;
Thrice a number, increased by nine, is fifteen.
Solution:
Given the thrice a number, increased by nine, is fifteen,
Let as the number be y, then we get,
3y + 9 = 15
Add -9 on both sides, then we get,
3y + 9 - 9 = 15 - 9
3y = 6
Both sides divided by 3, then we get,
`(3y) = 6/3`
`y = 2`
Answer:
Algebra expression for this problem is 3y + 9 = 15
Simplified algebra expression is y = 2.
3. Simplify Algebraic Expressions, 5x + 12 + 9y = -2x + 2 - 4
Solution:
Given algebra expression is, 5x + 12 + 9y = -2x + 2 - 4
Grouping and combining like terms, so we get,
5x + 12 + 9y = -2x - 2
Add 2x on both sides, we get
5x + 12 + 9y + 2x = -2x - 2 + 2x
7x + 9y + 12 = -2
Add 2 on both sides, we get
7x + 9y + 12 + 2 = -2 + 2
7x + 9y + 14 = 0
Answer: 7x + 9y + 14 = 0.
4. Simplify the algebra expression, 2a – (10a – 6a + 20) + 4a
Solution:
Given expression is 2a – (10a – 6a + 20) + 4a,
First, we grouping and combining the bracketed terms like this,
2a – (4a + 20) + 4a
Then brackets can be removed and combined the like terms,
We get the get the expression like this,
2a – 4a – 20 + 4a
2a and 4a combine to give 6a,
6a – 4a – 20
6a and -4a combine to give 2a,
2a – 20
2a = 20
Both sides divided by 2,
`(2a)/2 = 20/2`
`a = 10`
The answer is a = 10.
