Question

-4n+7+2n=1 a. 1 b. 3 c. -3 d. 4

Answer 1

-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 = $\frac{-6}{-2}$
Fifth, simplify $\frac{6}{-2}$ to $-\frac{6}{2}$ / Your problem should look like: n = $\frac{6}{2}$
Sixth, simplify $\frac{6}{2}$ to 3. / Your problem should look like: n = 3
 
Answer: n = 3 (B)
