Answer: 39

Work: So, we need to get x by itself, so we need to get -7 away from that side. So, we are going to add -7 to both sides, cancelling it on the side it's currently on. So, the equitation // answer is x = 39.

Check: Okay, let's add in 39 for x and solve the equitation. -7 + 39 = ? It equals 32. So, this is correct. I hope this helps, and Happy Holidays. :)

Consider this rational equation. 1 x 1 x − 2 = 1 4 use the least common denominator to simplify the rational equation into a sta

ratelena [41]

By using least common denominator, the rational equation can be expressed into a standard form quadratic equation as x^2 - 10x + 8 = 0.

In this question,

The rational equation is,

$\frac{1}{x}+\frac{1}{x-2}=\frac{1}{4}$

The standard form quadratic equation can be expressed as

$ax^{2} +bx+c=0$

The above rational equation can be expressed into a standard form quadratic equation by using least common denominator method as,

⇒ $\frac{1}{x}+\frac{1}{x-2}=\frac{1}{4}$

⇒ $\frac{(x-2)+x}{(x)(x-2)}=\frac{1}{4}$

⇒ $\frac{2x-2}{x^{2} -2x}=\frac{1}{4}$

⇒ $4(2x-2)=x^{2} -2x$

⇒ $8x-8=x^{2} -2x$

⇒ $x^{2} -2x-8x+8=0$

⇒ $x^{2} -10x+8=0$

Hence we can conclude that by using least common denominator, the rational equation can be expressed into a standard form quadratic equation as x^2 - 10x + 8 = 0.
