Can someone help please I am not sure

If you look at the problems, it requires combining like-term numbers and distributing (variables, coefficients, etc). So to combine like-term numbers, you should look for the same variables and/or coefficients. But, if there are parentheses '()' in the equations, you must distribute (multiply) them first and then combine like-terms.

For example, in problem #2 you see -2(3x + 15) 42

So first, distribute.

-6x -30 42

Now solve. Make sure you don't let the inequality sign confuse or trick you. It is just like when solving a two-step equation. So if I were you, I would pretend the inequality sign is an equal sign '='

Inverse operation: Turn -30 into +30 and add to 42.

-6x -30 42

     +30 +30

----------------------

        -6x 72

Inverse operation: Turn -6x into /-6 (division)

-6x/-6x 72

Now, here is the tricky part. When dividing or multiplying a negative coefficient (for example -6x is a negative coefficient) you MUST flip the inequality sign.

x -12

That's how you solve this and I hope this helps you :D
