-4n + 7 + 2n = 1
First, simplify -4n + 7 + 2n to -2n + 7. / Your problem should look like: -2n + 7 = 1
Second, subtract 7 from both sides. / Your problem should look like: -2n = 1 - 7
Third, simplify 1 - 7 to -6. / Your problem should look like: -2n = -6
Fourth, divide both sides by -2. / Your problem should look like: n = [tex] \frac{-6}{-2} [/tex]
Fifth, simplify [tex] \frac{6}{-2} [/tex] to [tex] -\frac{6}{2} [/tex] / Your problem should look like: n = [tex] \frac{6}{2} [/tex]
Sixth, simplify [tex] \frac{6}{2} [/tex] to 3. / Your problem should look like: n = 3
Answer: n = 3 (B)
