Question

Determine whether the given ordered pair is a solution to the system of equations.

9x−y=4
x+8y=2
​
Ordered pair: (4,0) Yes, it is a solution. No, it is not a solution

Answer 1

No it's not a solution to the simultaneous equation.

Answer 2

No, it is not a solution

Explanation:

to determine if (4, 0 ) is a solution

substitute x = 4 and y = 0 into the system of equations and if both are true, that is left side is equal to right side then the ordered pair is a solution.

9x - y = 9(4) - 0 = 36 - 0 = 36 ≠ 4 ← not true

x + 8y = 4 + 8(0) = 4 + 0 = 4 ≠ 2 ← not true

then (4, 0 ) is not a solution to the system of equations
