Chapter 2: Q41P (page 54)

Solve for all possible values of the real numbers $x$ and $y$ in the following equations. $(2 x - 3 y - 5) + i (x + 2 y + 1) = 0$

Short Answer

Expert verified

The answer is obtained:

$x = 1, y = - 1$

Step by step solution

Given information

It is given that $(2 x - 3 y - 5) + i (x + 2 y + 1) = 0$ .

Definition of a complex number

Every complex number can be expressed as:

z=a+bi

Whereaandbare both real numbers, z is the complex number, and i is known as iota, which makes z a complex number.

Begin by stating the given information

State the given information:

$(2 x - 3 y - 5) + i (x + 2 y + 1) = 0$

Equate like terms

Equate like terms from both sides:

$2 x - 3 y = 5 x + 2 y = - 1$

Solve the two equations to find the solutions

Multiply the second equation by $2$ and subtract it from the first equation:

$2 x - 3 y = 5 2 x + 4 y = - 2$

Continue evaluation as:

$- 7 y = 7 y = - 1 and 2 x = 5 + 3 (- 1) x = 1$

Thus, the final answer is obtained:

$x = 1, y = - 1$
