<h3>Answer:</h3>

D. 2x -3y = 18

<h3>Step-by-step explanation:</h3>

Multiply by 3, then rearrange.

... y = 2/3x -6

... 3y = 2x -18 . . . . . multiply by 3

... 0 = 2x -3y -18 . . . subtract 3y

... 18 = 2x -3y . . . . . add 18

... 2x - 3y - 18 . . . . . swap sides to match the form of the answers

8x+15 = 2x+39

8x =2x+24

6x = 24

x = 24/6 = 4

angle 4 = 2(4) +39 = 8+39 = 47

angle 6 = angle 4

angle 6 = 47 degrees

In this problem observing the table

For x=0

The value of y is equal to y=5

therefore

The initial value is 5

Substation method x-2y=5 ,<br> 3x-5y=8

valina [46]

$x-2y=5 \\
3x-5y=8 \\ \\
\hbox{solve the first equation for x:} \\
x-2y=5 \ \ \ |+2y \\
x=2y+5 \\ \\
\hbox{substitute 2y+5 for x in the second equation:} \\
3(2y+5)-5y=8 \\
6y+15-5y=8 \\
y+15=8 \ \ \ |-15 \\
y=-7 \\ \\
x=2y+5=2 \times (-7)+5=-14+5=-9 \\ \\
\boxed{(x,y)=(-9,-7)}$
