3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like: \(\frac{7}{-2}\) = x
Fourth, simplify \(\frac{7}{-2}\) to \(-\frac{7}{2}\) / Your problem should look like: \(- \frac{7}{2}\) = x
Fifth, switch sides. / Your problem should look like: x = \(-\frac{7}{2}\)
Answer as fraction: \(-\frac{7}{2}\)
Answer as decimal: -3.5
