Explanation:


\tt{3x - 10 + 5x = 2x - 13}

Combine like terms on left hand side. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.


\tt{3x + 5x - 10 = 2x - 13}


\tt{8x - 10 = 2x - 13}

Transpose 2x to left hand side and change it's sign.

Similarly , Transpose 10 to right hand side and change it's sign.


\tt{8x - 2x = - 13 + 10}


\tt{6x = - 3}

Divide both sides by 6


\tt{ (6x)/(6) = - (3)/(6)}


\tt{x = - (1)/(2)}


\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt {x = - (1)/(2)}}}}}} }

Hope I helped ! ♡

Have a wonderful day / night ! ㋡
