Question

Determine whether (7,8) is a solution of 7x+9y=11​

Answer 1

(7, 8) is NOT a solution to the equation

Explanation:

x = 7 and y = 8 so fill those into the equation

7(7) + 9(8) = 11

49 + 72 = 11

121 = 11

this makes the equation NOT true

So no, (7, 8) is NOT a solution to the equation
