I have a Summer Exam at the beginning of next week on all topics that we have done, so I decided to do Algebra, but I forgot how to do it, because it was a while ago; can anyone show me the method again please to memorize? Thanks in advance. Last edited by skipjack; June 1st, 2019 at 03:09 PM.

Memorise? What's that mean?

4x + 5 = 3x + 6 4x  3x + 5 = 3x  3x + 6 x + 5 = 6 x + 5  5 = 6  5 x = 1 One example isn't going to show you everything you need to know. You might be better off studying from a text.

Linear algebra is basically, $\displaystyle ax+b$. Using function $\displaystyle f(x)=ax+b$ Slope is $\displaystyle \tan \beta = \frac{y_1  y_2}{x_1  x_2}$ $\displaystyle f'(x)=x$ $\displaystyle \int_a^b f(x) = ax^2 + bx + c$ If you can solve the problem of the area between 3 intersecting lines, you're probably good to go.

That's a bit out of scope. He just seems to be solving for $x$.

I think Basko might have been trying to entertain us, and maybe had a few bevvies before posting.
