Question

3 added to twice
the number
o a number is equal to thrice the numbers what is number.Why?
​

Answer 1

Answer:

Let n = the unknown number

2n + 3 = n

Subtracting 3 from both sides, we get:

2n + 3 - 3 = n - 3

2n + 0 = n - 3

2n = n - 3

Now subtract n from both sides to isolate and solve for n:

2n - n = n - n - 3

(2 - 1)n = 0 - 3

(1)n = -3

n = -3

CHECK:

2n + 3 = n

2(-3) + 3 = -3

-6 + 3 = -3

-3 = -3

Therefore, n = -3 is the desired number.
