Q. Combine the like terms to create an equivalent expression.8x−1−2y+4
Identify like terms: Identify like terms in the expression 8x−1−2y+4. Like terms are terms that contain the same variable raised to the same power. Here, 8x and −2y are like terms with different variables, and −1 and +4 are like terms because they are both constants.
Combine constants: Combine the constants −1 and +4. To combine constants, simply add or subtract their values.−1+4=3
Write expression with combined terms: Write the expression with the combined constants and the like terms that contain variables.The expression becomes 8x−2y+3.
Check for remaining like terms: Check for any remaining like terms that can be combined. In the expression 8x−2y+3, there are no more like terms that can be combined, so this is the final simplified expression.
