Hi, umm pls help 1/6(x-5)=1/2(x+6), solve for x And can you please explain

Mumz [18]

Answer:

By solving the equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ we found that $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$

Explanation:

Given equation,

$\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ to find x

Step: 1 Cross multiply the denominators 2(x-5)=6(x+6)

Step: 2 Open brackets and simplify the term 2x-10=6x+36

Step: 3 Bring x terms on one side and simplify the equation the equation obtained is following,

2x-6x=36+10

-4x=46

$-x=\frac{46}{4}=\frac{23}{2}=11 \frac{1}{2}$

Therefore, we solved x value from the given equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ as $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$ .

How do u divide fraction?

agasfer [191]

To divide a fraction, you'd have to first write down the fractions being divided(Ex. 1/2 divided by 1/2). Next, convert the division sign in the problem to mulitplication while flipping the second fraction(Ex. 1/2 * 2/1).
Finally, Multiply the each of the fractions' numerators and denominators(Ex. 2/2). Simpify if nessasary. After you simpify(if nessasary), you will get your final answer(1).
