Final answer:
To find the missing coordinate of the ordered pair (?,4) that satisfies the equation 5x+2y-3=0, substitute y as 4 into the equation and solve for x. The missing coordinate is (-1,4).
Step-by-step explanation:
To find the missing coordinate of the ordered pair (?,4) that satisfies the equation 5x+2y-3=0, we can substitute the value of y as 4 into the equation and solve for x.
5x+2(4)-3=0
5x+8-3=0
5x+5=0
5x=-5
x=-1
Hence, the missing coordinate is (-1,4).
