Q. Find an expression which represents the sum of (−10x−1) and (−8x+5) in simplest terms.Answer:
Combine like terms: To find the sum of the two expressions, we combine like terms, which means adding the coefficients of the x terms together and the constant terms together.(−10x−1)+(−8x+5)=(−10x+(−8x))+(−1+5)
Add x terms: Now, we add the coefficients of the x terms: −10x+(−8x)=−18x.
Add constant terms: Next, we add the constant terms: −1+5=4.
Final expression: Combining the results from the previous steps, we get the final expression: −18x+4.This is the simplest form of the sum of the two given expressions.
