X/2-1/5=x/3+1/4<br>solve this equation ​
Alekssandra [29.7K]

Answer:

x=\frac{27}{10}

Step-by-step explanation:

\frac{x}{2}-\frac{1}{5}=\frac{x}{3}+\frac{1}{4}

\frac{x}{2}-\frac{1}{5}-\frac{x}{3}=\frac{x}{3}+\frac{1}{4}-\frac{x}{3}

-\frac{1}{5}+\frac{x}{6}=\frac{1}{4}

-\frac{1}{5}+\frac{x}{6}+\frac{1}{5}=\frac{1}{4}+\frac{1}{5}

\frac{x}{6}=\frac{9}{20}

\frac{6x}{6}=\frac{9\times \:6}{20}

x=\frac{27}{10}

Answer:

<h3>x = -2</h3>

Step-by-step explanation:

3[-x + (2 x + 1)] = x -1\\\\\mathrm{Expand\:}3\left(-x+\left(2x+1\right)\right):\quad 3x+3\\3x+3=x-1\\

Collect like terms

3x -x =-1-3

Add similar elements

2x = -4\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2x}{2}=\frac{-4}{2}\\\\Simplify\\\\x = -2
