10x - 4y=-20 find number that fit to x and y that get me -20

(0, 5) and (-2, 0)

Step-by-step explanation:

10x - 4y = -20

Let x = 0, then 10(0) - 4y = -20

                                  -4y = -20

                                ÷ -4   ÷ -4  

                                     y = 5

Let y = 0, then 10x - 4(0) = -20

                         10x -  0    = -20

                      ÷10               ÷10  

                             x         = -2

n = 9.2
