Question 88444: 6. The sum of two numbers is 28. The larger number, y, is 4 more than the smaller number, x. Write two equations for this system and solve to find x and y.
Give your answer as an ordered pair without parentheses or spaces, as in x,y.
You can put this solution on YOUR website! X+Y=28 X=28-Y
Y=X+4 NOW SUBSTITUTE (X+4) FOR Y IN THE FIRST EQUATION & SOLVE FOR X
X=28-(X+4)
X=28-X-4
2X=28-4
X=24/2
X=12 ANSWER.
Y=12+4
Y=16 ANSWER. (12,16)
PROOF
12+16=28
28=28
