Answer: -6x + 14
Step-by-step explanation: Let's simplify this problem using the distributive property. The first thing we want to do is change the -7 to plus a negative 7.
Now we can distribute or multiply this -2 times each of the terms inside the set of parentheses.
So we get -2(3x) + -2(-7) and this simplifies to -6x + 14.
