Is x=-2 a solution to x 3 − x 5 = 2 3 ? \frac { x } { 3 } - \frac { x } { 5 } = \frac { 2 } { 3 } ? 3 x − 5 x = 3 2 ?

Question

Is x=-2 a solution to   x 3 − x 5 = 2 3 ? \frac { x } { 3 } - \frac { x } { 5 } = \frac { 2 } { 3 } ? 3 x ​ − 5 x ​ = 3 2 ​ ?

Final Answer : false, Explanation :   When you substitute x = -2 into the equation, you get   − 2 3 − − 2 5 = − 10 + 6 15 = − 4 15 \frac{-2}{3} - \frac{-2}{5} = \frac{-10 + 6}{15} = \frac{-4}{15} 3 − 2 ​ − 5 − 2 ​ = 15 − 10 + 6 ​ = 15 − 4 ​  , which is not equal to   2 3 \frac{2}{3} 3 2 ​  .
