Answer:
x=4
Step-by-step explanation:
1. 7x+56=14x+28 using distributive property (with the number of stes you need to have, this may count as 2)
2. 56=7x+28 by subtracting 7x from each side
3. 28=7x by subtracting 28 from both sides
4. x=4 by dividng by 7
5. plug back into equation
7(4)+56=14(4+2)
28+56=14(6)
84=84
