Question

X/3+x/7<2 , how do i solve ?

Answer 1

B

Explanation:

`(x)/(3)+(x)/(7)<2`

Since the least common multiple of 3 and 7 is 21, multiply both sides by 21:

`7x+3x<42 \\\\10x<42`

Divide both sides by 10 to isolate x:

`x<(42)/(10)\\\\\\x<(21)/(5)`

Therefore, the correct answer is choice B. Hope this helps!
