7. What is the solution to 9x = -63?<br> A. x=54<br> B. x= 7<br> C. x= -7<br> D. x = -54

Dmitry [639]

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.
