Answer :
Let's solve the equation [tex]\(-7x = 28\)[/tex] step-by-step:
1. Identify the equation: We have [tex]\(-7x = 28\)[/tex].
2. Isolate the variable: To solve for [tex]\(x\)[/tex], we need to get [tex]\(x\)[/tex] by itself on one side of the equation. We do this by dividing both sides of the equation by [tex]\(-7\)[/tex], the coefficient of [tex]\(x\)[/tex].
[tex]\[
x = \frac{28}{-7}
\][/tex]
3. Perform the division: When we divide 28 by [tex]\(-7\)[/tex], we get [tex]\(-4\)[/tex].
So, the solution is [tex]\(x = -4\)[/tex].
Therefore, the correct answer is C. -4.
