Question

5x – 3y < 12x - 4y > 16Identify 3 solutions to the system of inequalities .. hurry up please

Answer 1

(-1,5) , (-2,-6) and (-3,-7)

Let's plot that system below:

5x – 3y < 12

x - 4y > 16

The solutions will be located at the darker blue area

So we can locate three solutions, (-1,5) , (-2,-6) and (-3,-7)

Like this:

Let's test them

(-1,-5)

5(-1) -3(-5) <12

10 < 12 True

(-1) -4(-5)>16

-1 +20>16

19>16 True

(-2,-6)

5(-2) -3(-6) <12

-10+18<12 True

-2 -4(-6) >16
