Question

What is the value of x that satisfies the equation15(x + 9) = -21?

Answer 1

To find:

The value of x that satisfies the equation 15(x + 9) = -21.

Solution:

The value of x that satisfies the equation is the solution of the equation.

Solve the equation as follows:

`\begin{gathered} 15(x+9)=-21 \\ 15x+135=-21 \\ 15x=-21-135 \\ 15x=-156 \\ x=(-156)/(15) \\ x=-10.4 \end{gathered}`

Thus, x = 10.4 satisfies the given equation.
