4x^2 - 24x + 7 = 3<br> I don't understand how to get to the final answer of <br> x= 3 ± 2sqrt2

sergey [27]

4x² - 24x +7-3 =0
4x² - 24x + 4=0 /:4
x² - 6x +1=0
Use formula

$x = \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a} 

For our equation a=1, b= - 6, c = 1

x= (6+/- \sqrt{36-4)}/2 = \frac{-6+/- \sqrt{32} }{2} = \frac{-6+/- \sqrt{16*2} }{2} = \frac{-6+/-4 \sqrt{2} }{2} 

= -3 +/- 2\sqrt{2}

3x+4y=-23 <br> 2y-x=-19 <br> What is the solution (x,y) to the systems of equations above?

Shkiper50 [21]

If we multiply the bottom equation by 2 and move x to the right, it becomes:

4y = 2x-38

Now we can substitute it for the 4y in the top equation:

3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3

Then 4y = 2*3-38 => y = -8

So the solution is (3,-8)
