-2x = 4
First, divide both sides by -2. / Your problem should look like: x = [tex] \frac{4}{-2} [/tex]
Second, simplify [tex] \frac{4}{-2} [/tex] to [tex] -\frac{4}{2} [/tex] / Your problem should look like: x = [tex] -\frac{4}{2} [/tex]
Third, simplify [tex] \frac{4}{2} [/tex] to 2. / Your problem should look like: x = -2
Answer: x = -2
