Question

x+5/2+x/3=20 solve this equations​

Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

$\sf{x + \frac{5}{2} + \frac{x}{3} = 20 }$

Taking LCM

$\sf{ \frac{6x + 15 + 2x}{6} = 20 } \\ \\ \sf{ \frac{8x + 15}{6} = 20 }$

By cross multiplication

$\sf {8x + 15 = 20(6)} \\ \\ \sf{8x + 15 = 120} \\ \\ \sf{8x + 15 - 120 = 0} \\ \\ \sf{8x - 105 = 0} \\ \\ \sf{8x = 105}\\ \\ \sf{x = \frac{105}{8}}\\ \\ \sf{x = 13.125}$

$\rule{200}{2}$

x = 13.125
