20 is equal to 20 and not less. So, (6,-8) is not the solution to inequality 2x-y<20
Step-by-step explanation:
We need to find if (6, -8) a solution to the inequality 2x − y < 20 ?
putting x =6 and y = -8 in the given inequality
[tex]2x-y<20\\2(6)-(-8)<20\\12+8 < 20\\20 < 20(not\,\,true)[/tex]
Since 20 is equal to 20 and not less. So, (6,-8) is not the solution to inequality 2x-y<20
