x - 2y = 4
Add 2y to both sides: x = 4 + 2y
Subtract 4 from both sides: x - 4 = 2y
Divide both sides by 2: (x - 4)/2 = y or y = 0.5x - 2

4 (apples) plus 3 (apples) = 7 (apples). 4 (cows) + 3 (cows) = 7 (cows) 4 (x2y) + 3 (x2y) = 7 (x2y)
How do you factor 3x3-x2y plus 12x-4y?
3x3 - x2y + 12x - 4y = x2*(3x - y) + 4*(3x - y) = (x2 + 4)*(3x - y)

4
If y varies inversely as the square of x and y equals 4 when x equals 5 findy y when x is 2?
y varies inversely as x2 so y = c/x2 for some constant c. When x = 5, y = 4 So c = x2y = 100 that is y = 100/x2 Then, when x = 2, y = 100/4 = 25
How do you solve 4y x2y?
Times the numbers together, 4 x 2 = 8 Times the independent variables, y x y = y2 answer = 8y2
