help please Based on the lesson, identify the first operation needed to solve the following equation. 2x + 3 = 11 addition subtraction multiplication division
You would need to subtract 3, then divide by 2.
^^^
Make sense?

I find it to be kinda tricky cause you could technically divide first, but would be a pain...
Whatever you do to one side of an equation you have to also do to the other, basics of algebra.
We are going to try to get x by itself, so we can solve for it.
So if you have 2x+3=11 The first thing I would do is just subtract 3 from both sides so then we would have 2x = 8 which is alot closer to having x by itself.
At that point we could easily divide both sides by 2. 2x/2 = 8/2 therefore x = 4
How is that? I always like to ad or subtract numbers first that are not being multiplied by variable. After variable is isolated (possibly with a multiplier out front like 2x) we can then divide to solve for x.
Any more clear now?
