$\begin{gathered}\large {\boxed{\sf{\mid{\overline {\underline {\star ANSWER ::}}}\mid}}}\end{gathered}$

Given :-

• 3(x - 9) = 3x - 9

To Find :-

• The error in the given Equation.

Solution :-

By distributive Property under Subraction :

$\star \: \large \boxed{ \sf{a(b - c) = ab - ac}} \: \star$

⟼ Let us assume 3(x - 9) = a(b - c)

Here,

a = 3,

b = x,

c = 9.

⟼ By substituting the values in the equation

a(b - c) = ab - ac

3(x - 9) = 3(x) - 3(9)

3(x - 9) = 3x - 27

CORRECT EQUATION : 3(x - 9) = 3x - 27
