Question

verify that x=3 is a root of 3x-5=7-x

​

Answer 1

Question.

➝ Is x = 3 a root of [ $\sf\green{3x-5 = 7-x}$

Solution.

putting value of x in $\sf\green{3x-5 = 7-x}$

➝ $\sf\green{3x-5 = 7-x}$

➝ $\sf\green{3(3)-5 = 7-( 3 )}$

➝ $\sf\green{ 9-5 = 7-3 }$

➝$\sf\green{ 4 = 4}$hence profed.

R.H.S and l.H.S is equal so, x = 3 is a root of this equation.
