Answer

$x=1\frac{9}{11}$

Work Step by Step

Solve for x. $\frac{x}{5}-\frac{x}{4}=\frac{x-2}{2}$ Multiply each side by 20, the least common multiple, to convert fractions to whole numbers. $20\times(\frac{x}{5}-\frac{x}{4})=20\times(\frac{x-2}{2})$ Apply the distributive property. $4x-5x=10(x-2)$ $-x=10x-20$ Subtract 10x from each side. $-x-10x=10x-20-10x$ $-11x=-20$ Divide each side by -11. $-11x\div-11=-20\div-11$ $x=\frac{20}{11}$ $x=1\frac{9}{11}$
