Answer:

65 + 13i

Step-by-step explanation:

reminder that i² = - 1

13i(1 - 5i) ← multiply each term in the parenthesis by 13i

= 13i - 65i²

= 13i - 65(- 1)

= 13i + 65

= 65 + 13i ← in standard form

What is the solution to this system of linear equations2x+3y=3 and 7x-3y24

Kay [80]

For this case we have a system of two equations with two unknowns:

$2x + 3y = 3\\7x-3y = 24$

We follow the steps below:

We add the equations:

$9x = 27$

We divide between 9 on both sides of the equation:

$x = \frac {27} {9}\\x = 3$

We substitute the value of "x" in the first equation and find the value of y:

$2 (3) + 3y = 3\\6 + 3y = 3\\3y = 3-6\\3y = -3\\y = \frac {-3} {3}\\y = -1$

Thus, the solution of the system is: (3, -1)

Answer:

(3, -1)
