I don't know how to get the variables to cancel out. 3x - 6y = 3 7x - 5y = -11 This is about the elimination method.
From equation get the value of x and then put in the 2nd equation. \[x=\frac{ 3+6y }{ 3 }\] after solving you will get value of Y then put that value in new or any of you above given equations.
