Question : 34 of 120

Marks: +1, -0

If

\;\;{3x-2}/{3}+\;\;{2x+3}/{2}

=x+ {7}/{6}

then the value of

\;\;{5x-2}/{4}

is :

- 1 / 3
1 / 4
-1 /12
1 / 12

Solution:

Given that

\;\;{3x-2}/{3}+\;\;{2x+3}/{2}=x+\;\;{7}/{6}

⇒\;\;{6x-4+6x+9}/{6}=\;\;{6x+7}/{6}

⇒12x+5=6x+7

6x=2

∴x=1/3

Now, putting the value of x in

{5x-2}/4

\;\;{5x-2}/{4}=\;\;{5×(\;\;{1}/{3})-2}/{4}

=\;\;{\;\;{5}/{3}-2}/{4}

=\;\;{5-6}/{4×3}=\;\;{-1}/{12}
