Question

check whether the value given is a solution to the given equation or not-

4p -3=13 (p=-4)

Answer 1

$$\begin{gathered} \mathrm{The}\mathrm{given}\mathrm{equation}\mathrm{is}, \\ 4\mathrm{p}-3=13 \\ \mathrm{LHS}=4\mathrm{p}-3=4\times \left(-4\right)-3=-16-3=-19 \\ \mathrm{RHS}=13 \\ \mathrm{Since},\mathrm{LHS}\ne \mathrm{RHS} \\ \mathrm{So},\mathrm{p}=-4\mathrm{is}\mathrm{not}\mathrm{the}\mathrm{solution}\mathrm{of}\mathrm{the}\mathrm{given}\mathrm{equation}. \end{gathered}$$
