Determine the missing coordinate in the ordered pair (x,3/2) so that it will satisfy the equation, 5x+y=1

Answer 1

The missing coordinate in this case is the x coordinate.

The equation 5x + y = 1 represents all the ordered pairs (x,y) that will make this equation "true"

So to find the x coordinate that goes with the given y coordinate we substitute in the 3/2 fory in the equation

5x + 3/2 = 1 Subtract 3/2 from both sides to get....

5x = -1/2 Divide both sides by 5 to get.....

x = -1/10

Answer 2

5x + 3/2 = 1

5x = 1 - 3/2

5x = -1/2

x = -1/10
