Yeah, it's useful to be able to manipulate formulae. Just like converting Fahrenheit to Celsius and backwards, it can be useful to be able to rearrange other algebraic expressions...
Algebra is therefore a great tool, that allows us to manipulate unknown expressions, to see the rates of change, and to then go back later on and "plug in" the real figures to get answers. For real life situations, as you say, bear in mind that everything we do is greatly assisted by computers, which run on a lot of maths. Insurance you will, or do pay is calculated by complex mathematical expressions.
Linear (and more often, higher-order) equations are incredibly useful for looking at natural relationships (weight vs age, health vs weight, you name the relationship, and something can be deduced).
Factorisation is more of a useful tool to help us solve complicated mathematical problems.

Algebra is used all the time. RT=D, calculating mileage, and ratio and proportion problems are classic examples.
I use factoring when calculating probabilities, or just to make long division easier on those rare occasions when I lack access to the nearly ubiquitous electronic calculator. Factoring and algebraic manipulation also helps simplify equations on business spreadsheets.
I personally don't use linear equations very frequently in my job, though I can say that it is very difficult to use anything you do not know. Knowledge is power, and the more you know, the more options you have. Knowing how to solve linear equations opens up new worlds of possibility for you. NOT knowing how to solve them is like boxing with one arm in a sling. You might win a few rounds against weak opponents, but most people in your weight class will smack you up good.

you'll use algebra a million and uncomplicated geometry, no longer something else. Assuming you're not any more going to take a occupation in engineering, physics, or mathematics, algebra 2 is a load of crap and regardless of math courses you pick to take after which will be, too. each and every thing after calculus is understood and far extra problematic to carry close than stepped ahead philosophy alongside with existentialism so a recommendations as i'm in contact. a minimum of you could communicate about existentialism. There are not countless those who would ever discover themselves engaged in a verbal substitute about theoretical mathematics. in order that that you recognize i can fairly wrap my head round math, i'm completely linguistically geared, so my answer is amazingly biased.

I do CAD for a commercial cabinet company and I find myself using Geometry all the time and some of my old trig and algebra. You never know where it will pop up. This is something I just happened to fall into but I am really glad I took the math I did as it does come in handy.

In any sort of engineering or financial work. Even in every day life you'll most likely use algebra and linear equations but you probably won't think of it in that sense.

Looking back on high school, the four most valuable classes I took were typing, woodshop, algebra, and geometry.

If you write the Sports page for a Newspaper, probably not. If you just use arithmetic to balance your checkbook, no. If you have anything at all to do with technology, yes.
