Solve {l}{2x-y=7}{y=3}

$$\left\{ \begin{array} { l } { 2 x - y = 7 } \\ { y = 3 } \end{array} \right.$$

Solve for x, y

$$x=5$$

$$y=3$$

Solution Steps

Consider the first equation. Insert the known values of variables into the equation.

$$2x-3=7$$

Add 3 to both sides.

$$2x=7+3$$

Add 7 and 3 to get 10.

$$2x=10$$

Divide both sides by 2.

$$x=\frac{10}{2}$$

Divide 10 by 2 to get 5.

$$x=5$$

The system is now solved.

$$x=5 y=3$$
