Ineed this one now i messed up on the other lol

The first one is X, then the second one would be X+1 ( adding one, makes it consecutive).

Now you have X + X+1 = 667

Simplify:

2x +1 = 667

Subtract 1 from each side:

2x = 666

Divide both sides by 2:

x = 666 /2

x = 333

The first marker is 333

The second marker = 333 +1 = 334

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
