Chapter 14.2, Problem 3OE

To determine

To find: The value of $s$ and $t$ .

Answer to Problem 3OE

The value of $s=4$ and $t=1$ .

Explanation of Solution

Given:

The given expression is $\left(s+2\right)i+j=6i+tj$ .

Calculation:

Consider the given expression is,

  $\left(s+2\right)i+j=6i+tj$

Then,

  $\begin{array}{l}si+2i+j=6i+tj\\ si+j=4i+tj\end{array}$

Match the right side of the above equation with the left then,

  $\begin{array}{l}s=4\\ t=1\end{array}$
