3n + 2n = 25 5n = 25 n = 5

2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13

On = 2n - 1 so O13 = 2*13 - 1 = 26 - 1 = 25

-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13

6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333

2n + 19 = -7 2n = -7 - 19 2n = -26 n= -13

2n + 5 = 25 < ---------------- Write the Equation 2n = 20

2n plus 7 equals 19 2n equals 12 n equals 6

On = 2n - 1 so O13 = 2*13 - 1 = 26 - 1 = 25

-7 = 2n + 19 Subtract 19 from both side -26 = 2n Divide by 2 on both sides n = -13

6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333

On = 2n - 1 then O13 = 2*13 - 1 = 26 - 1 = 25

You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.

2n + 8 = -142n = -22n = -11
