Answer: C
Step-by-step explanation:

Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48

Therefore,
Option D is the correct answer.
-1 because x is 4 so you just plug it in and 4-8 is -4 and -4/4 is -1.
Answer:
I'd say you need to be more specific.
Step-by-step explanation:
"Different" doesn't tell you much.
Consider the equations ...
These equations are "different", but they are <em>dependent</em>.
_____
I'd mentally (or actually) put the equations in the same form and compare the coefficients of x and y. If they have different ratios, the system is independent and consistent.
If they have the same ratio, the system will not have a single solution. Whether there is no solution or an infinite number of solutions depends on the constant, which I would examine next.
The system above can be put in the form
In both cases, the ratio of the x coefficient to the y coefficient is 2/-1 = 4/-2 = -2. This means the lines are at least parallel, if not identical. The numbers in the second equation are all 2 times the numbers in the first equation, so the equations are <em>dependent</em>, and there are an infinite number of solutions. (Both describe the same line.)
If the second equation were 4x -2y = 1, then the two equations would be describing parallel lines, so they would be called <em>inconsistent</em>.
