Solve {l}{45y+15x=60}{y=60}

$$\left\{ \begin{array} { l } { 45 y + 15 x = 60 } \\ { y = 60 } \end{array} \right.$$

Solve for y, x

$$x=-176$$

$$y=60$$

Solution Steps

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

$$45\times 60+15x=60$$

Multiply 45 and 60 to get 2700.

$$2700+15x=60$$

Subtract 2700 from both sides.

$$15x=60-2700$$

Subtract 2700 from 60 to get -2640.

$$15x=-2640$$

Divide both sides by 15.

$$x=\frac{-2640}{15}$$

Divide -2640 by 15 to get -176.

$$x=-176$$

The system is now solved.

$$y=60 x=-176$$
