In that case, how are you getting the second equation ( 4 + 1/2*x = y)? What statement imply existence of that equation?

You have the word problem, now write it out into an equation.srsd said:I miss stated the problem.....One number is 4 plus 1/2 of a number. The sum of the numbers is 31. Find the numbers.

\(\displaystyle 4 + \frac{1}{2}x = y\)

\(\displaystyle x + y = 31\)

Solve the system.
