Solve for \( h \):

\[ \frac{2}{5}h - 7 = \frac{12}{5}h - 2h + 3 \]

Asked by Reynolds630

Answer (3)

5 h − 7 2 ​ = 5 h − 2 h + 3 12 ​ 5 h − 7 2 ​ = 3 h + 3 12 ​ 2 ( 3 h + 3 ) = 12 ( 5 h − 7 ) 6 h + 6 = 60 h − 84 6 h − 60 h = − 84 − 6 − 54 h = − 90 h = − 54 − 90 ​ = 9 15 ​ = 3 5 ​ ​

The equation 5 2 ​ h − 7 = 5 12 ​ h − 2 h + 3 simplifies to a contradiction, indicating that there are no values of h that satisfy it. This means the equation has no solution. h cannot take any real number value to make this equation true.
