To determine

To calculate: Model and solve the system.

Answer to Problem 1CB

  $x=3,y=4$

Explanation of Solution

Given information:

  $\begin{array}{l}y=x+1\\ 2x+y=10\end{array}$

Calculation:

Let’s put the value of $y$ from the equation one to equation two,

  $\therefore 2x+x+1=10$

  $\therefore 3x=9$

  $\therefore x=3$

By, putting the value of $x$ in the equation one,

  $y=3+1=4$
