What I would do here is substitute "5y -87" for x in the first ecquation, since the second equation is already in the form "x=..." so:
4*(5y-87)+9y=29
getting rid of the bracket:
20y-348+9y=29
adding up:
29y=29+348
29y= 377
dividing by 29:
y=13
and now we can calculate x, which is 5*13-87=65-87=-22
so x=-22
Answer:
<h2>2560000</h2>
Step-by-step explanation:
2500 x 4= 10000
10,000 x 4=40,000
40,000 x 4=160,000
160,000 x 4=640,000
640,000 x 4= 2560000
(5 - 2i)(1 - 2i) You can solve this as though it was (x - 2)(x + 3): use foil
F: 5*1 = 5
O: 5 *(-2i) = - 10i
I : -2i * (1) = - 2i
L: (-2i)(-2i) This may take a bit. There's a few signs hanging around.
L: (-2 * -2)*(i * i)
L: 4 (i *i)
L: 4(-1)
L: - 4 So combine these results.
FOIL: 5 - 10i - 2i - 4 Group the like terms
FOIL: 5 - 4 - 10i - 2i Now collect them
FOIL: 1 - 12i <<<<<<< Answer
So you do 24x 113.5 that ends up as 2724 pages
