Simplifying
x + (2x + 3) = (x + 3)(x + 4)

Reorder the terms:
x + (3 + 2x) = (x + 3)(x + 4)

Remove parenthesis around (3 + 2x)
x + 3 + 2x = (x + 3)(x + 4)

Reorder the terms:
3 + x + 2x = (x + 3)(x + 4)

Combine like terms: x + 2x = 3x
3 + 3x = (x + 3)(x + 4)

Reorder the terms:
3 + 3x = (3 + x)(x + 4)

Reorder the terms:
3 + 3x = (3 + x)(4 + x)

Multiply (3 + x) * (4 + x)
3 + 3x = (3(4 + x) + x(4 + x))
3 + 3x = ((4 * 3 + x * 3) + x(4 + x))
3 + 3x = ((12 + 3x) + x(4 + x))
3 + 3x = (12 + 3x + (4 * x + x * x))
3 + 3x = (12 + 3x + (4x + x2))

Combine like terms: 3x + 4x = 7x
3 + 3x = (12 + 7x + x2)

Solving
3 + 3x = 12 + 7x + x2

Solving for variable 'x'.
