Dividing by 0 is not defined so let s take x different from 4 and -4 and then we can write:

Thanks
Bell is the tallest person at 52 inches, Con is the shortest person at 42 inches. So 54 - 42 = 12
Ratios are fractions. Equivalent means equal, if you change one set of numbers, you have to change the second set of numbers so then that Ratio or Equivalent fraction stays equal on both sides.
Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
