What is 5( x - 3 ) = 5x - 15?
Volgvan

\tt5( x - 3 ) = 5x - 15 \\  \tt5x - 15 = 5x - 15 \\ \tt5x - 5x =  - 15 + 15 \\ \tt\bcancel{5x} - \bcancel{5x} =  \bcancel{- 15} + \bcancel{15} \\ \boxed{\tt0 = 0}

  • The answer is <u>0</u><u>.</u>
  • LHS = RHS, hence verified.

<u>Value of x (substitute 0 in the place of x).</u>

\tt5( (0) - 3 ) = 5(0) - 15 \\  \tt0 - 15 = 0 - 15 \\  \tt \boxed{\tt -15 = -15}

  • So, value of x is <u>0</u><u>.</u>
