The lines are parallel.

In order to figure this out, let's start off by simplifying both equations as much as we can:
2y = 16 + 4x
Divide by 2
y = 2x + 8

Remember that the slope of that equation is '2' since 'm' in the equation y = mx + b represents slope.

Simplify the next equation:
6y - 30 = 12 x
6y = 12x + 30
Divide by 6:
y = 2x + 5

As you can tell, this line also has a slope of 2.
Parallel lines is defined as two lines that have the same slope. Knowing this, we can infer that these two lines are parallel.

Please do it in substitution method. Thanks.​
alina1380 [7]

Answer:  No solution

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

x - 3y = 2   →     x = 3y + 2

2x - 6y = 6

2(3y + 2) - 6y = 6        <em>substituted x with 3y+2</em>

6y + 4 - 6y = 6            <em>distributed 2 into 3y+2</em>

        4        = 6           <em>simplified (6y - 6y = 0)</em>

4 = 6 is a FALSE statement so there is NO SOLUTION

K compounded monthly 12
T time 15 years
A=10,000×(1+0.0625÷12)^(12×15)
