Well I am pretty bored right now so i decided to go on a website and practice some algebra for next week.
Let us see if you can figure these out. A reminder. These should be pretty easy.

Just take them you want. I will tell the answers later or you could just pm the answers. karma if you do well.

1: 2(x - 3) = x + 4

2: 5x - (12 + 3x) = 2

3: 15 - (6 - 8x) = 25

4: 2(x - 3) + 5(x + 1) = 34

5: (6x - 8) - (x + 4) = 6 - x

6: (5 - x) - (10 - 2x) = 6 - x - 5

7: 5(x - 2) + 2(3x + 2) = 27

8: 3(1 - 3x) - (x + 5) = 20

9: 31 + 2(3x - 4) = 5(2x + 3)

10: 12( 2x - 3) - 6(x - 8) = 120

Those are really easy algebra problems. That's like 7th Grade Algebra right there.

Not right enough.

80% right.

No more karma. This seems to be too easy. Still many of you are having problems with one or two.

Try some Calculus

y = (x+1)^(x+1)^(x+1) Find y'

pfft. Go do some real maths:

Complex Numbers

One root of:

z^4 - 10z^3 + 42z^2 - 82z + 65 = 0

Is:

3 + 2j

---

Solve the equation, hence, find the other 3 roots.
