Four times a number is three times the difference of that number and one

andrey2020 [161]

Answer: the number is -3

Step-by-step explanation:

Four times a number is three times the difference of that number and one

Let the number be x. Four times the number means 4×x = 4x

three times the difference of that number and one. This means

Difference of the number and one is (x-1). Three times the difference of the number and one would be 3(x-)

Four times a number = three times the difference of that number and one. Therefore,

4x = 3(x-1)

Opening the bracket

4x = 3x -3

4x-3x = -3

x =-3

Check

4×-3 =3(-3-1)

-12 = -3×4

-12 = -12

So the number is -3

X^2-6x-4=0,

Rzqust [24]

Use quadratic formula since we can't factor

for 0=ax²+bx+c
$x= \frac{-b+/-\sqrt{b^2-4ac}}{2a}$

so, for
0=1x²-6x-4
a=1
b=-6
c=-4

$x= \frac{-(-6)+/-\sqrt{(-6)^2-4(1)(-4)}}{2(1)}$
$x= \frac{6+/-\sqrt{36+16}}{2}$
$x= \frac{6+/-\sqrt{52}}{2}$
$x= \frac{6+/-2\sqrt{13}}{2}$
$x= 3+/-\sqrt{13}$

the solutions are x=3+√13 and x=3-√13
or aprox
x≈6.61 and x≈-0.61
