2x + 4 = 2x + 2
2x - 2x = 2 - 4
0 = -2 ......(when the variables drop out and ur left with an untrue statement, this means there are no solutions)

2x + 5 = 2x + 5
2x - 2x = 5  - 5
0 = 0.....(when the variables drop out and ur left with a true statement, this means there is infinite solutions)

so the two possible solutions when the variables drop out are : no solutions and infinite solutions

Reptile [31]

Answer:

8

Step-by-step explanation:

Given:

Annuity at time (n + 1) = 13.776

(1 + i)ⁿ = 2.476

Now,

S_{n/i}=\frac{(1+i)^n-1}{d}

here, d = \frac{i}{1-i}

thus,

13.776=\frac{2.476-1}{d}

or

d = 0.1071

therefore,

d = \frac{i}{1+i}

or

0.1071 = \frac{i}{1+i}

or

0.1071 + 0.1071i = i

or

i = 0.1199

now,

(1 + i)ⁿ = 2.476

or

(1 + 0.1199)ⁿ = 2.476

1.1199ⁿ = 2.476

taking log both sides

n × log(1.1199) = log(2.476)

or

n = 8.006 ≈ 8

hence,

the answer is 8
