Question

How many solutions does this linear system have?

Answer 1

Answer:

B- one solution: (1,-4)

Step-by-step explanation:

(1,-4)

y = -6x +2

-4 = -6(1) +2

-4 =-4

(1,-4)

-12x - 2y = -4

-12(1) -2(-4) = -4

-12 + 8 =-4

-4 = -4

if you put the value x and y into both equation you can find the solution

Answer 2

Answer:

Hi there!

The correct answer is: D. Infinite number of solutions

Step-by-step explanation:

in this case you can use the substitution method to solve these linear equations

since y = -6x +2 you can plug this into the equation -12x -2y = -4

-12x - 2(-6x +2) = -4 this comes out to be -12x + 12x -4 = -4

then you simplify down to 0x=0
