We are given some equations and asked to find out which equation is true when k = -15
Note that an equation is true when left-hand side of the equation is equal to the right-hand side of the equation.
Let us substitute k = -15 into each of the given equation
A)
[tex]\begin{gathered} 3k-11=-34 \\ 3(-15)-11=-34_{} \\ -45-11=-34 \\ -56\ne-34 \end{gathered}[/tex]As you can see, the equation is not true since the left-hand side is not equal to the right-hand side.
