Solve {l}{a=2b*3}{b=17-12*11/2}

$$\left. \begin{array} { l } { a = 2 b \times 3 } \\ { b = 17 - 12 \times 1 \frac { 1 } { 2 } } \end{array} \right.$$

Solve for a, b

$$a=-6$$

$$b=-1$$

Solution Steps

Consider the second equation. Multiply 1 and 2 to get 2.

$$b=17-12\times \frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$b=17-12\times \frac{3}{2}$$

Multiply 12 and \frac{3}{2} to get 18.

$$b=17-18$$

Subtract 18 from 17 to get -1.

$$b=-1$$

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

$$a=2\left(-1\right)\times 3$$

Multiply 2 and -1 to get -2.

$$a=-2\times 3$$

Multiply -2 and 3 to get -6.

$$a=-6$$

The system is now solved.

$$a=-6 b=-1$$
