Decide whether (7,1) is a solution of the equation. 5X + 9y = -3
To determine whether (7,1) is a solution of the equation 5x + 9y = -3, we substitute the values of x and y into the equation and check if the equation is satisfied.
Substituting x = 7 and y = 1 into the equation:
5(7) + 9(1) = -3
35 + 9 = -3
44 = -3
Since 44 does not equal -3, the equation is not satisfied when x = 7 and y = 1. Therefore, (7,1) is not a solution of the equation.
