Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26

Consider 8x2 - 48x = -104.

Answer:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

$8x^2-48x=-104$

Divide by 8:

$x^2-6x=-13$

Now complete the squares so the left side is a perfect square of a binomial:

$x^2-6x+9=-13+9=-4$

Factoring the perfect square:

$(x-3)^2=-4$

Taking the square root:

$x-3=\sqrt{-4}$

The square root of a negative number is an imaginary number:

$x-3=\pm 2\mathbf{i}$

Solving for x:

$x=3\pm 2\mathbf{i}$

The solutions are:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Answer:

Any negative number would be a counterexample.

Step-by-step explanation:

Since negative numbers get smaller as you multiply them by a larger number, this would prove this conjecture false.
