Q.

21

.

(-3)^{x}=4

\newline

2 x=12

Exponential Equation: Step $1$ : Solve the first equation $(-3)^{x}=4$ . $\newline$ We know that any real number raised to any real exponent cannot result in a negative number when the base is negative and the exponent is not a fraction. Therefore, there is no real solution for $(-3)^{x}=4$ .
Linear Equation: Step $2$ : Solve the second equation $2x=12$ . $\newline$ Divide both sides by $2$ to isolate $x$ : $\newline$ $\frac{2x}{2} = \frac{12}{2}$ , $\newline$ $x = 6$ .
