\frac{2\left(2x-3\right)}{10}+\frac{5\left(x+4\right)}{10}=x
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 5 and 2 is 10. Multiply \frac{2x-3}{5} times \frac{2}{2}. Multiply \frac{x+4}{2} times \frac{5}{5}.
\frac{2\left(2x-3\right)+5\left(x+4\right)}{10}=x
Since \frac{2\left(2x-3\right)}{10} and \frac{5\left(x+4\right)}{10} have the same denominator, add them by adding their numerators.
\frac{4x-6+5x+20}{10}=x
Do the multiplications in 2\left(2x-3\right)+5\left(x+4\right).
\frac{9x+14}{10}=x
Combine like terms in 4x-6+5x+20.
\frac{9}{10}x+\frac{7}{5}=x
Divide each term of 9x+14 by 10 to get \frac{9}{10}x+\frac{7}{5}.
\frac{9}{10}x+\frac{7}{5}-x=0
Subtract x from both sides.
-\frac{1}{10}x+\frac{7}{5}=0
Combine \frac{9}{10}x and -x to get -\frac{1}{10}x.
-\frac{1}{10}x=-\frac{7}{5}
Subtract \frac{7}{5} from both sides. Anything subtracted from zero gives its negation.
x=-\frac{7}{5}\left(-10\right)
Multiply both sides by -10, the reciprocal of -\frac{1}{10}.
x=\frac{-7\left(-10\right)}{5}
Express -\frac{7}{5}\left(-10\right) as a single fraction.
x=\frac{70}{5}
Multiply -7 and -10 to get 70.
x=14
Divide 70 by 5 to get 14.
