2x + 3y = 3 and x + 6y = -3

jekas [21]

Answer:

Step-by-step explanation:

Multiplying x+6y=-3 with 2 so its equal to first eqn,

Eliminating,

2x + 3y = 3 (1)

2x +12y = -6 (2) (because subtracting)

------------------

-9y =9

∴y=-1

eq. y in 1

2x -3=3

2x=3+3

x=6/2

Solve for x. A. x =9 B. x = 3 C. x = 4 D. x = 27

meriva

Your formula for this is $9^{2} =x(24+x)$ and $81=24x+ x^{2}$ . Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.

Can you explain it and help me out please

Anarel [89]

Answer:

Step-by-step explanation:

2x² - 4x - 3 = 0

$x= \frac{-b+/-\sqrt{b^{2}-4ac} }{2a} \\\\x= \frac{-(-4)+/-\sqrt{(-4)^{2}-4*2*(-3)} }{2*2} \\\\x= \frac{4+/-\sqrt{16+24} }{4} \\\\x= \frac{4+/-\sqrt{40} }{4} = \frac{4+/-2\sqrt{10} }{4}=\frac{2+/-\sqrt{10} }{2}$
