Answer

Step-by-step explanation

To know how many solutions this system of linear equations have, we willl need to solve it.

2x + 3y = 6

-8x - 12y = -20

Making x the subject of formula in the first equation

2x + 3y = 6

2x = -3y + 6

Divide through by 2

(2x/2) = (-3y/2) + (6/2)

x = (-3y/2) + 3

Substituting this for x in the second equation

-8x - 12y = -20

x = (-3y/2) + 3

-8 (-3
