1. (4x-2)(5x+7)=0
<=> x=0.5 or x=7/5
2. (3x)(1+5+8)
3. hgfhfd
4. 2y+7x=25

11y+3x=89
5. (3x)(1+5+8) = 42x
6. (Original post by mr T 999)
2y+7x=25

11y+3x=89
Can't quite do those in my head yet
7. fdsa
8. Y=In x - In y
9. 2 In (x/7 ( -5))=-7
10. gfds
11. (x-3)(x-12)+9=7x-2
12. (Original post by mr T 999)
Y=In x - In y
well this is actually just a function, there is a curve which is a solution to this, i.e x=1/y *e^y, so I can't solve it

(Original post by mr T 999)
(x-3)(x-12)+9=7x-2

x=11+/- 0.5*root(446) ?

possibly mistakes in there
