Question

3+x/4=5 find the value of x

Answer 1

Answer:-

$\\ \sf\longmapsto 3+\dfrac{x}{4}=5$

• Take LCM on left side

$\\ \sf\longmapsto \dfrac{12+x}{4}=5$

• Use Cross multiplication

$\\ \sf\longmapsto 12+x=4\times 5$

$\\ \sf\longmapsto 12+x=20$

• Take 12 to right side

$\\ \sf\longmapsto x=20-12$

$\\ \sf\longmapsto x=8$
