5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
3n + 6 = n + 202n = 14n = 7
3n+1=7 3*2+1=7
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
4n
n=-9.6
-add 3n to both sides -subtract 2 from both sides -cancel out the both -divide 28 by 7.
3n + 4n = -14 7n /7 = -14 /7 n = -2
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
No. 3n is not a factor of 3n + 7.
No. 3n is not a factor of 3n + 7.
n = -6
