In which step is the error? Step 1: Let x = 1 and y = 1. Step 2: By substitution xy = y^2. Step 3: Multiplying both sides by 1, xy= y^2. Step 4: Adding x^2 to both sides, x^2xy=x^2y^2. Step 5: Factoring, x(xy)=(x+y)(xy).

If 4X + Y =H, Then X is equal to? 4X + Y =H Move Y to other side by subtracting Y from both sides. 4X + Y  Y = H  Y Combine terms. 4X = H  Y Now divide both sides by 4 to get 1X. 4X/4 = (H  Y)/4 X = (HY)4 or (1/4)(HY)
