Question

How do you solve x+1x−3=4−12x2−2x−3?

Answer 1

Answer: x = 1/7

Step by step explanation :

$x + 1x - 3 = 4 - 12x \times 2 - 2x - 3$

Cancel equal terms on both sides of the equation.

$= > x + 1x = 4 - 12x \times 2 - 2x$

When the term has a coefficient of 1, it doesn't have to be written.

$= > x + x = 4 - 12x \times 2 - 2x$

Calculate the product by multiplying the numbers.

$= > x + x = 4 - 24x - 2x$

Collect the like terms by adding their coefficients.

$= > 2x = 4 - 24x - 2x$

Collect the like terms by calculating the sum or difference of their coefficients.

$= > 2x = 4 - 26x$

Move variable to the left side and change its sign.

$= > 2x + 26x = 4$

Collect the like terms by adding their coefficients.

$= > 28x = 4$

Divide both sides of the equation by 28

$= > x = \frac{1}{7}$

$= > x = 7 {}^{ - 1}$
