Question

Solve x/2 ±x/4 ±x/5 =10
solve it now​

Answer 1

Answer:

Step-by-step explanation:

FIRST WAY,

$\frac{x}{2}+\frac{x}{4}+\frac{x}{5}=10\\or, \frac{10x+5x+4x}{20} =10\\or, \frac{19x}{20} =10\\or, x=\frac{10*20}{19} \\or, x=\frac{200}{19}=10.53(app)/10\frac{10}{19}$

SECOND WAY,

$\frac{x}{2}-\frac{x}{4}-\frac{x}{5}=10\\or,\frac{10x-5x-4x}{20} =10\\or,\frac{x}{20}=10 \\or,x=200$
