  • The value of x

{ \textbf{\textsf{ \underline{ \underline{{Solution \: :}{\quad}}}}}}

 \\ ⇢ \:  \tt \:  \frac{7x - 7}{7}  =  \frac{4x - 2}{2}  \\  \\   \\

By cross multiplication we get,

 \\ ⇢ \:  \tt \:  2({7x - 7)} =  7({4x  + 2)} \\  \\  \\ ⇢ \tt14x - 14 = 28x  +  14 \:  \:  \\  \\  \\ ⇢ \tt \: 14x - 28x =   14 + 14 \\  \\  \\  \tt⇢  \: - 14x = 28 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \\  \tt \:⇢  - x =  \frac{28}{14}   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \\  \tt \:⇢  - x =  2   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\ \\  \tt \:⇢  x =   - 2   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

  • Hence, The value of x = -2
