\underline{\bold{Hello!!}}


2(x - 3) + 5(x + 2) = 2 \\  \\  =  > 2x - 6 + 5x + 10 = 2 \\  \\  =  > 7x + 4 = 2 \\  \\  =  > 7x = 2 - 4 \\  \\  =  > 7x =  - 2 \\  \\  =  > x =  \frac{ - 2}{7}


\underline{\bold{Verification:-}}



2(x - 3) + 5(x + 2) = 2

Put x = - 2 / 7

 =  > 2( \frac{ - 2}{7}   + 3) + 5( \frac{  - 2}{7} + 2 ) = 2 \\  \\  =  >  \frac{ - 4}{7}  + 6 -  \frac{10}{7}  + 10 = 2 \\  \\  =  >   \frac{ - 4}{7}  -  \frac{10}{7}  + 6 + 10 = 2 \\  \\  =  >  \frac{ - 4 - 10}{7}  + 16 = 2 \\  \\  =  >  \frac{ - 14}{7}  + 16 = 2 \\  \\  =  >  - 2 + 16 = 2 \\  \\  =  > 14 = 2


LHS # RHS









\textbf{Hope it helps!}
