Answer:
-14x + 21
Step-by-step explanation:
Use the distributive property to solve. Multiply -7 by each number in parentheses. -7 times 2x is -14 x and -7 time -3 is 21 (a negative times a negative is a positive). You should get -14x + 21 as an answer. You are no longer able to simplify any farther from there.
