Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Answer:
6a+4b-14
Step-by-step explanation:
For this, we have to use the distributive property.
This means we multiply each value in the parentheses by 2.
2*3a=6a
2*2b=4b
2*(-7)=-14
So our equation is:
6a+4b-14
