Question

(2)The equation form of "Sum of two consecutive numbers is equal to third consecutive number (take x as unknown)" is​. . . . . .

Answer 1

Answer:

3x

Step-by-step explanation:

$x + 2x = 3x \\ 3x = 3x \\ = 3x$

it's too simple

Answer 2

Answer:

The equation form is 2x + 1 = x + 2

Step-by-step explanation:

Let the first number be x, then it's consecutive number would be (x + 1), then the next consecutive number would be (x + 2)

Then,

Sum of two consecutive numbers = third consecutive number

x + (x + 1) = (x + 2)

x + x + 1 = x + 2

2x + 1 = x + 2

Hence,

The equation form is 2x + 1 = x + 2

We can also solve for x,

2x + 1 = x + 2

2x - x = 2 - 1

x = 1

Then,

(x + 1) = (1 + 1) = 2

(x + 2) = (1 + 2) = 3

We can also check this,

x + (x + 1) = (x + 2)

1 + 2 = 3

3 = 3

LHS = RHS
