x - 3y = -6
2x - y = 3
-3y + x = -6 y + 2x = 3
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = 3y - 6
// Plug this in for variable x in equation [2]
[2] 2•(3y-6) - y = 3
[2] 5y = 15
// Solve equation [2] for the variable y
[2] 5y = 15
[2] y = 3
// By now we know this much :
x = 3y-6
y = 3
// Use the y value to solve for x
x = 3(3)-6 = 3
Solution :
{x,y} = {3,3}
-FrxziteTheLxoser- Hoped this help! :)
If you dont understand the answer is {x,y = {3,3}
