You can put this solution on YOUR website! SUM IS 84=======DIFFERENCE IS =30
X+Y====84====YOUR SUM
X-Y====30====YOUR DIFFERENCE
30 + 84==114==ADD TOGETHER
X=72========HALF OF YOUR ANSWER
SOLVE FOR Y
72+Y=84==========YOUR SUM
Y=84-72=======SUBTRACT SUM FROM ANSWER
Y=12
X==72,,,Y==12
You can put this solution on YOUR website! Equation 1:
Equation 2:
Solve equation 2 for A
Now plug (B + 30) into equation 1 for A
Equation 1:
Combine like terms
Subtract 30 from both sides
Divide both sides by 2
Now plug 27 into equation 2 for B
