Find the solutions to the following equation:(x + 1)/(3)  -  (2x - 1)/(x)  =  - 1

Answers

Answer:

x=1+/-4i

Step-by-step explanation:

(x+1)/3-(2x-1)/x=-1

find the common denominator,

in this case, it's going to be 3x.

(x^2+x)/3x-(6x-3)/3x=-1

(x^2+x-6x+3)/3x=-1

x^2-5x+3=-3x

x^2-5x-(-3x)+3=0

x^2-5x+3x+3=0

x^2-2x+3=0

apply the quadratic formula in order to find the roots for x.

Since ax^2+bx+c=0, in this case,

a=1, b=-2, c=3

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

x=(-b+/-sqrt(b^2-4ac))/2a

x=(2+/-sqrt(4-12))/2

x=(2+/-8i)/2

x=1+/-4i

How to do two step equations simple please help and you can do the example on this one: 2x+5=21

Answers

Answer: The answer here is x=2

Step-by-step explanation:

This is a linear equation, take 5x to other side ut will change a sign then solve for x.

2x+5=21

2x=21-5

2x=16

Lastly divide by 2 both sides to get 2

Using these coordinates, (3, 1/4) and (-2, -1) write an equation in Point-Slope, Slope-Intercept, and Standard Form.

Answers

Answer here\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } =   (-1 -   (1)/(4))/(-2 -  3) =  ( - (5)/(4))/(-5)= ( - (5)/(4)\cdot4)/(-5\cdot4) =(-5)/( -20)  =\boxed{ \bf{  (1)/(4)}}

The slope is 1/4.

The equation in point-slope form is:
y - (-1) = 1/4(x - (-2))
\boxed{\bf{y + 1 = (1)/(4)(x+2)}}

In slope-intercept form, it is:
y + 1 = 1/4(x+2)
\boxed{\bf{y = (1)/(4)x - (1)/(2)}}

In Standard form it is:
y = 1/4x - 1/2
1/2 = 1/4x - y
Multiply both sides by 4
2 = x - 4y
\boxed{\bf{x-4y=2}}

I hope that helps. :)
