Answer:

Step-by-step explanation:
1. Combine like terms
2y-7y = -5y
-5y=5
2. Divide by -5 and the answer is 
2/7 because both 8 and 28 are divisible by 4
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.
Answer:
I would solve this as Simplify the matrix.
Step-by-step explanation:
I would do 5+9
Then i would do 16+2
Then the 4 would be by it self
14=18=4
Then if you need to solve it more then i would just add 14 18 and 4 together
