Question

X-6y>5
7x+2y>4


Is (10,-2) a solution of the system?

Answer 1

Yes

Explanation:

10-6(-2)>5

10+12>5

22>5

(10, -2) is a solution for x-6y>5

7(10)+2(-2)>4

70-4>4

66>4

(10, -2) is a solution for 7x+2y>4

(10,-2) is a solution for both equations, therefore it is a solution of the system.
