1. what is the solution to the system of equations?
3x - 6y = -12
x - 2y = -8
(a) use the substitution method to justify that the given system of equations has no solution.
(b) what do you know about the two lines in this system of equations?

Step-by-step explanation:

(a)

3x - 6y = -12.,(1)

x - 2y = -8.…(2)

from equation (2),by adding 2y to both sides, x= -8 + 2y(3)

Let's substitute the value of x in equation (1)

3(-8 + 2y) - 6y = -12

-24 + 6y - 6y = -12

6y - 6y = 12..,..(4)

From equation (4) we can see that both equations (1) and (2) has no solutions for x and y

(b)They are two parallel lines of slope of 2 and intercepts on y at 2 and 4

step-by-step explanation:

im not sure what the answer is

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
