B) 15

EXPLANATION

The given polynomial is

$23 {x}^{5} + 12 {x}^{2} + 19 { x }^{3} + 15 {x}^{6}$

We arrange this polynomial in ascending powers of x to obtain the standard form;

Solve the system of equations below algebraically <br> 2x+3y=6 and -5x+2y=4

Charra [1.4K]

Steps
I’m using elimination so I’m trying to get rid of y
To do that I multiply the first equation by 2 and the second by -3. Then solve
4x + 6x = 12
15x + -6x = -12
—————————
19x + 0 = 0
Divid by 19 to get x to one side. 0/19 is 0 so
X= 0
Plug that into an equation so 0 + 3y = 6
Divid by 3 and y = 2
Answer x = 0 y = 2
