How do I solve two step equations?

1. 3x+5=-16

x = - 7

Step-by-step explanation:

Given

3x + 5 = - 16 (subtract 5 from both sides)

3x = - 21 (divide both sides by 3)

x = - 7

Two-step equations can get more difficult the higher the numbers get, but they're not too hard!; )

To solve 3x+5=-16:

First subtract 5 from each side

Now its 3x=-21

Next divide 3 from each side

You get x=-7!

Always check your work! To check your work plug your answer "-7" into x.

So it looks like this: 3 (-7) + 5=-16 then distribute and solve!

You'll get - 16=-16, that means its correct/true!
