Answer:

1, 3, 4, and 10

Step-by-step explanation:

To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:

y = 3(2) - 5

y = 6 - 5

y = 1.

To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.

(4) = 3x - 5

Add 5 to both sides

9 = 3x

Divide both sides by 3

3 = x

Do the same with 7

(7) = 3x - 5

Add 5

12 = 3x

Divide by 3

4 = x

For the last one, you're given x so substitute it into the equation:

y = 3(5) - 5

y = 15 - 5

y = 10
