Not sure how to solve this

  (x, y) = (0, -14), (2, -8), (3, -5)

Step-by-step explanation:

Put the given values into the equation and solve.

x = 0

  y = 3·0 -14 = -14

y = -8

  -8 = 3x -14

  6 = 3x . . . . . . add 14

  2 = x . . . . . . . divide by 3

x = 3

  y = 3·3 -14 = -5

The ordered pairs in your table are ...

  (x, y) = (0, -14), (2, -8), (3, -5)

Comment on the approach

In this problem, you are only asked for one x-value for a given y-value. If there were more, you would solve the equation generically (x = (y+14)/3) and use that to compute the desired values of x.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
