2x=y ×+y=36 x=Ed's age y=His brothers age Then you plug in Y into the secound equation. ×+2×=36. You then add the two x together. 3x=36 The to get x by itself you take 36 and dive by 3 to get 12. x=12 Then plug 12 into the equation 12+y=36 Then get y by itself. y=24. So, Ed's age is 12 and Ed's brother's age is 24.
