\left\{ \begin{array} { l } { 3 x = 6 } \\ { x - 2 y = 7 } \end{array} \right.
Solve for x, y
x=2
y = -\frac{5}{2} = -2\frac{1}{2} = -2.5

x=\frac{6}{3}
Consider the first equation. Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
2-2y=7
Consider the second equation. Insert the known values of variables into the equation.
-2y=7-2
Subtract 2 from both sides.
-2y=5
Subtract 2 from 7 to get 5.
y=-\frac{5}{2}
Divide both sides by -2.
x=2 y=-\frac{5}{2}
The system is now solved.
