4x - 5y = 0 (#1)

4x + 6y = 12 (#2 x 2)

-11y = -12 I subtracted them

y = 12/11

back in #1

4x = 5(12)/11

x = 15/11

it is about inequalities. i have to solve them graphically and shade the solution set.then i have to identify teo points within the solution set and two points not within the solution set. they are y is less than 2x-3

and y is greater than or equal to -3x. how do you solve for those equations ?
