Simplifying the Expression: (1/3x−3)+(−3/4x−5)
This article will guide you through simplifying the expression (1/3x−3)+(−3/4x−5). We'll break down the steps and explain the concepts involved.
Understanding the Expression
The expression contains two sets of parentheses, each representing a binomial. A binomial is a polynomial with two terms. In this case, the terms are:
- 1/3x and -3 in the first binomial
- -3/4x and -5 in the second binomial
Combining Like Terms
To simplify the expression, we need to combine like terms. Like terms are terms that have the same variable and exponent.
- x terms: 1/3x and -3/4x
- constant terms: -3 and -5
Step 1: Combining x terms:
- Find a common denominator for 1/3 and -3/4: 12
- Convert the fractions: (4/12)x + (-9/12)x = -5/12x
Step 2: Combining constant terms:
- Simply add the constants: -3 + (-5) = -8
Final Simplified Expression
After combining the like terms, the simplified expression is:
-5/12x - 8
Therefore, (1/3x−3)+(−3/4x−5) simplifies to -5/12x - 8.
