To find: the variable we will solve for and the equation which we will choose to substitute into
Answer to Problem 13P
Express
Explanation of Solution
Given information:
Consider the following equations:
Prefer to choose the equation that has a variable with coefficient 1
Here, the equation
From equation
We will choose equation
Now will solve the equations just to show how will the calculation part becomes easy on choosing the equation that has a variable with coefficient 1(although the solution has not been asked in this question)
