Let Aequals [Start 2 By 2 Matrix 1st Row 1st Column 1 2nd Column 4 2nd Row 1st Column negative 3 2nd Column negative 12 EndMatrix ]and bequals [Start 2 By 1 Matrix 1st Row 1st Column b 1 2nd Row 1st Column b 2 EndMatrix ]. Show that the equation Axequals b does not have a solution for some choices of b​, and describe the set of all b for which Axequals b does have a solution.

i think the correct option is the second option.

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
