Question

What is incorrect about this method?

Answer 1

Hello,

This method is correct!

`(4)/(5) *x+ (7)/(2) = (3)/(10) \\ ==\textgreater\ (5)/(4)*( (4)/(5) *x+ (7)/(2)) = (5)/(4)* (3)/(10) \\ ==\textgreater\ (5)/(4)* (4)/(5) *x+ (5)/(4)*(7)/(2)=(5)/(4)* (3)/(10) \\ ==\textgreater\ x+ (35)/(8) = (3)/(8) \\ ==\textgreater\ x+ (35)/(8)-(35)/(8) = (3)/(8) -(35)/(8)\\ ==\textgreater\ x = -(32)/(8)\\ Maybe\ this\ line \ is\ missing\\ x=-4`
