Given the equation 9x = -63, the numerical value of x is -7.
<h3>What is the solution to the given equation?</h3>
Given the equation in the question;
9x = -63
To determine the value of x, we divide both sides by the coefficient of x.
9x = -63
9x/9 = -63/9
x = -7
Given the equation 9x = -63, the numerical value of x is -7.
