Solve {l}{x-2y+1=0}{x-1=0}

$$\left\{ \begin{array} { l } { x - 2 y + 1 = 0 } \\ { x - 1 = 0 } \end{array} \right.$$

Solve for x, y

$$x=1$$

$$y=1$$

Solution Steps

Consider the second equation. Add 1 to both sides. Anything plus zero gives itself.

$$x=1$$

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

$$1-2y+1=0$$

Add 1 and 1 to get 2.

$$2-2y=0$$

Subtract 2 from both sides. Anything subtracted from zero gives its negation.

$$-2y=-2$$

Divide both sides by -2.

$$y=\frac{-2}{-2}$$

Divide -2 by -2 to get 1.

$$y=1$$

The system is now solved.

$$x=1 y=1$$
