Chapter 6: Q12. (page 361)

Use substitution to solve each system of equations.
$y = 鈭� 4 x 6 x 鈭� y = 30$

Short Answer

Expert verified

The required solution is represented by $x = 3$ and $y = 鈭� 12$ .

Step by step solution

Step 1. Number the provided equations.

Make consideration that,

$y = 鈭� 4 x ...... (1) 6 x 鈭� y = 30 ...... (2)$

Step 2. Take the help of equation (1) to get the value of x after it use the obtained value to get the value of y.

The equation (1) is representing the value of y in the form of an expression so use it for the equation (2) to extract the value of x.

$6 x 鈭� (鈭� 4 x) = 30 6 x + 4 x = 30 10 x = 30 x = \frac{30}{10} = 3$

Use the obtained value of x into equation (1) to get the value of y.

$\begin{matrix} y = 鈭� 4 鈰� 3 \\ = 鈭� 12 \end{matrix}$

Step 3. Write the conclusion.

The obtained value of x and y represents the required solution that is $x = 3$ and $y = 鈭� 12$ .
