Solve the equation. Use words or set notation to identify equations that have no solution, or equations that are true for all
real numbers.
-$$12 ( x - 3 ) = 6 ( 2 x + 5 ) - 66$$
A) $\{ - 36 \}$
B) $\{ 0 \}$
C) $\{ x \mid x$ is a real number $\}$
D) $\varnothing$

Expanding both sides of the equation gives $12x - 36 = 12x + 30 - 66$. Simplifying the right side results in $12x - 36 = 12x - 36$, which is true for all real numbers $x$, indicating the equation is an identity.

Solve the Equation 12(x−3)=6(2x+5)−6612 ( x - 3 ) = 6 ( 2 x + 5 ) - 6612(x−3)=6(2x+5)−66

Solve the Equation $12 ( x - 3 ) = 6 ( 2 x + 5 ) - 66$
