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.

6+4=10
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
