Math Problem Statement

For each ordered pair, determine whether it is a solution to 7x - 2y = 13.

Solution

Let's check if each of the ordered pairs (x,y)(x, y) is a solution to the equation 7x2y=137x - 2y = 13.

Step-by-step process:

We'll substitute each xx and yy value from the ordered pairs into the equation and check if the left-hand side equals 13.

  1. For (3,4)(3, 4): 7(3)2(4)=218=137(3) - 2(4) = 21 - 8 = 13 Yes, this is a solution.

  2. For (1,3)(1, -3): 7(1)2(3)=7+6=137(1) - 2(-3) = 7 + 6 = 13 Yes, this is a solution.

  3. For (5,0)(-5, 0): 7(5)2(0)=35+0=357(-5) - 2(0) = -35 + 0 = -35 No, this is not a solution.

  4. For (2,5)(-2, 5): 7(2)2(5)=1410=247(-2) - 2(5) = -14 - 10 = -24 No, this is not a solution.

Final Answer:

(x,y)(x, y)Is it a solution?
(3,4)(3, 4)Yes
(1,3)(1, -3)Yes
(5,0)(-5, 0)No
(2,5)(-2, 5)No
