Question

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

Answer 1

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

• The answer is 0.
• LHS = RHS, hence verified.

Value of x (substitute 0 in the place of x).

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

• So, value of x is 0.
