Final answer:
The expression −(12y+14)−(12y+14) is equivalent to -24y - 28.
Step-by-step explanation:
The expression −(12y+14)−(12y+14) can be simplified by applying the distributive property to each term in the expression.
Step 1: Distribute the negative sign to each term within the parentheses by multiplying -1 to both terms.
−(12y+14)−(12y+14) = -1 times 12y - 1 times 14 - 1 times 12y - 1 times 14
Step 2: Combine like terms.
-12y - 14 - 12y - 14 = -24y - 28
Therefore, the expression −(12y+14)−(12y+14) is equivalent to -24y - 28\
