Solve {l}{3g-h=7}{g=3}

$$\left. \begin{array} { l } { 3 g - h = 7 } \\ { g = 3 } \end{array} \right.$$

Solve for g, h

$$g=3$$

$$h=2$$

Solution Steps

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

$$3\times 3-h=7$$

Multiply 3 and 3 to get 9.

$$9-h=7$$

Subtract 9 from both sides.

$$-h=7-9$$

Subtract 9 from 7 to get -2.

$$-h=-2$$

Divide both sides by -1.

$$h=\frac{-2}{-1}$$

Fraction \frac{-2}{-1} can be simplified to 2 by removing the negative sign from both the numerator and the denominator.

$$h=2$$

The system is now solved.

$$g=3 h=2$$
