Question

10-5+x/3-8x+5/2=20 use LCM method ​

Answer 1

Answer:

x=-75/46

Step-by-step explanation:

$10 - 5 + \frac{x}{3} - 8x + \frac{5}{2} = 20$

The LCM of the denominator is 6 because both 2 and 3 can go into 6.

$10 - 5 + \frac{2x}{6} - 8x + \frac{15}{6} = 20$

Multiply all terms by 6 to drop the fraction. Make sure to multiply both sides of the equation

$60 - 30 + 2x - 48x + 15 = 120$

Put all x values on one side

$2x - 48x = 120 - 60 + 30 - 15$

$- 46x = 75$

$x = - \frac{75}{46}$
