How to solve equations with variable in denominator?

1 answer:

4 0

In general you can multiply through by the LCD

For example solve :-

2/x + 1 / (1+ x) = 11/12

The LCD is 12x(x + 1).

Now we multiply each term by 12x(x + 1)

2*12(x+1) + 12x = 11x(x + 1)

and this is solved in the usual way.

Solve for x - 3 (x - 4) = 2x + 4x + 5

In-s [12.5K]

Answer:

$x=\frac{7}{9}$

Step-by-step explanation:

-3(x-4)=2x+4x+5

distribute -3 into (x-4)

-3x+12=2x+4x+5

combine like terms

-3x+12=6x+5

subtract 6x on both sides

-3x-6x+12=5

combine like terms again

-9x+12=5

subtract 12 on both sides

-9x=-7

divide both sides with -9

$\frac{-9x}{-9} \frac{-7}{-9}$

x= $\frac{7}{9\\}$

hope this helps

Given PQRS is a square, solve for x.

ivanzaharov [21]

Answer:

x = 11

Step-by-step explanation:

The angles in a square are right , that is 90°

The diagonals bisect the angles , then

6x - 21 = 45 ( add 21 to both sides )

6x = 66 ( divide both sides by 6 )

x = 11
