3n + 2n = 25 5n = 25 n = 5
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
42 = 2n + 7Subtract 7 from each side of the equation:35 = 2nDivide each side by 2:17.5 = n

n = 1
3n + 2n = 25 5n = 25 n = 5
2n plus 7 equals 19 2n equals 12 n equals 6
-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13
If: 2n = 1 Then: n = 1/2 or 0.5
42 = 2n + 7Subtract 7 from each side of the equation:35 = 2nDivide each side by 2:17.5 = n

Given that 2n = 6 + n, subtract n from each side and n = 6
If: -6n-2n = 16 Then: n = -2
n = 1
n=-9.6
2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13
When n=53, then 2n + 1 = 107
