Question

For the equation x+5y=40, find the missing value in the following ordered pair: (−5,?)

Answer 1

To find the missing y value in the ordered pair (-5, ?) for the equation x + 5y = 40, substitute -5 for x and solve for y to find that y equals 9, completing the pair as (-5, 9).

Step-by-step explanation:

For the equation x + 5y = 40, we want to find the missing value in the following ordered pair: (-5, ?). To find the missing y value, we'll substitute x = -5 into the equation and solve for y:

1. Start with the original equation: x + 5y = 40.
2. Substitute x with -5: -5 + 5y = 40.
3. Add 5 to both sides to get: 5y = 40 + 5.
4. After calculation, this simplifies to: 5y = 45.
5. Divide both sides by 5 to find y: y = 45 / 5.
6. After dividing, we get: y = 9.

So, the missing value in the ordered pair (-5, ?) for the equation x + 5y = 40 is 9, and the complete pair is (-5, 9).
