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

3x3 - x2y + 12x - 4y = x2*(3x - y) + 4*(3x - y) = (x2 + 4)*(3x - y)

One way to use four fours to make 25 is 4 + 4 + 4 + √4, which equals 25.

T = 4x + 8 Subtract 8 from both sides: T - 8 = 4x Divide both sides by 4: T/4 - 2 = x or x = T/4 - 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

Times the numbers together, 4 x 2 = 8 Times the independent variables, y x y = y2 answer = 8y2
