In order to find the solution you just have to answer one of the equations to solve for x then plug it in for the other ones. so lets start. so x equals 1/3
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
A and E
Whole numbers and integers
x + 2y = 4
2x - 2y = 5
Adding both the equations:
x + 2y + 2x - 2y = 9
3x = 9
x = 3
y = 4-x /2 = 1/2
