Find a solution for 5x+4y=-30 and 3x-9y=-18

{5x + 4y = -30

{3x - 9y = -18        | : 3

{5x + 4y = -30

{x - 3y = -6          | + 3y

{5x + 4y = -30

{x = 3y - 6

{5(3y - 6) + 4y = -30

{x = 3y - 6

{15y - 30 + 4y = -30         | + 30

{x = 3y - 6

{19y = 0              | : 19

{x = 3y - 6

{y = 0

{x = 3 · 0 - 6

{y = 0

{x = -6

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
