1 Find the sum of -3y-4 and 8y+2.
Solution:
[tex] ( - 3y - 4) + (8y + 2) \\ \\ - 3y + 8y = 5y \\ - 4 + 2 = 2 \\ \\ ( - 3y - 4) + (8y + 2) = 5y - 2[/tex]
Answer:
5y-2
2. What must be added to 13m + 11 to obtain 0?
Solution:
[Simply stay on the variables and constants and change only their signs (i.e., + to -, - to +) to acquire the neutralizer binomial to 13m + 11.]
Answer:
-13m-11
3. Find the difference when 7x-3 is subtracted from 11x-2.
Solution:
[tex](11x - 2) - (7x - 3) \\ \\ 11x - 7x = 4x \\ ( - 2) - ( - 3) = 1 \\ \\ (11x - 2) - (7x - 3) = 4x + 1[/tex]
Answer:
4x+1
