Tell whether the ordered pair is a solution of the equation. Just substitute the given x and y to see if the equation “works”. Write “solution” if it works and “not solution” if it doesn’t.

Question

y=4x + 2; (2,10)
2x + y = 5; (7, 5)

Answer 1

For the equation y = 4x + 2 and the ordered pair (2,10), we substitute x = 2 and y = 10 into the equation:

10 = 4(2) + 2
10 = 8 + 2
10 = 10

Since both sides of the equation are equal, the ordered pair (2,10) is a solution.

For the equation 2x + y = 5 and the ordered pair (7,5), we substitute x = 7 and y = 5 into the equation:

2(7) + 5 = 5
14 + 5 = 5
19 = 5

Since the left side of the equation does not equal the right side, the ordered pair (7,5) is not a solution.
