Question

If x/4+2/3=11/2 then x =

Answer 1

Question:

$\frac{x}{4}+\frac{2}{3}=\frac{11}{2}$.Then x =

Given:

$\frac{x}{4}+\frac{2}{3}=\frac{11}{2}$

To Find:

The value of x

Solution:

$\frac{x}{4}+\frac{2}{3}=\frac{11}{2}$

$\frac{x}{4}+\frac{2}{3}=\frac{11}{2}\\\\\\\textsf{LCM-12}\\\\\\\frac{x}{4}\times\frac{3}{3}+\frac{2}{3}\times\frac{4}{4}=\frac{11}{2}\\\\\\\frac{3x}{12}+\frac{8}{12}=\frac{11}{2}\\\\\\\frac{3x+8}{12}=\frac{11}{2}\\\\\\\frac{3x}{12}=\frac{11}{2}-\frac{8}{12}\\\\\\\frac{3x}{12}=\frac{3}{12}\\\\\\x=\frac{3}{12}\times\frac{12}{3}\\\\\\x=1$

Check:

$\\\frac{x}{4}+\frac{2}{3}=\frac{11}{2}\\\\\\\textsf{Substitute x =1}\\\\\\\frac{1}{4}+\frac{2}{3}=\frac{11}{2}\\\\\\\textsf{LCM=12}\\\\\\\frac{1}{4}\times\frac{3}{3}+\frac{2}{3}\times\frac{4}{4}=\frac{11}{2}\\\\\\\frac{3}{12}+\frac{8}{12}=\frac{11}{2}\\\\\\\frac{11}{2}=\frac{11}{2}\\\\\\\textsf{LHS=RHS}$

Answer:

• x = 1
