A) 2
B) 3
C) 1
D) 0
Correct Answer: C
Solution :
We have, \[\frac{3}{4}(7x-1)-\left( 2x-\frac{1-x}{2} \right)=x+\frac{3}{2}\] \[\Rightarrow \] \[\left( \frac{21}{4}x-\frac{3}{4} \right)-\left( \frac{4x-1+x}{2} \right)=x+\frac{3}{2}\] \[\Rightarrow \] \[\frac{21}{4}x-\frac{3}{4}-\frac{5x-1}{2}=x+\frac{3}{2}\] \[\Rightarrow \] \[\frac{21x-10x-4x}{4}=\frac{6+3-2}{4}\Rightarrow x=1\]You need to login to perform this action.
