Chapter 9.2, Problem 8OE

To determine

To find: Thesolution of the given equations by using substitution method.

Answer to Problem 8OE

The solution of the given equations by using substitution method is $a=3\text{and }b=1$ .

Explanation of Solution

Given information:

The given equationsare,

  $\begin{array}{l}b=a-2\\ b=1\end{array}$

The given equation is,

  $b=a-2$

Substitute $1$ for $b$ .

  $\begin{array}{l}1=a-2\\ a=1+2\\ a=3\end{array}$

Thus, the solution of the given equations by using substitution method is $a=3\text{and }b=1$ .
