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

Answer 1

The answer to the above statement is b. 3

Answer 2

-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 =
`(-6)/(-2)`
Fifth, simplify
`(6)/(-2)` to
`-(6)/(2)` / Your problem should look like: n =
`(6)/(2)`
Sixth, simplify
`(6)/(2)` to 3. / Your problem should look like: n = 3

Answer: n = 3 (B)
