Step-by-step explanation:

The functions are given below as


\begin{gathered} 2x-y=7----(1) \\ 3x+y=3-----(2) \end{gathered}

Step 1:

Express the function in the form of thr equation of the line below


y=mx+b

By doing this to equation(1), we will have


\begin{gathered} 2x-y=7 \\ y=2x-7----(3) \end{gathered}

By doing gthis to equation (2), we will have


\begin{gathered} 3x+y=3 \\ y=-3x+3----(4) \end{gathered}

Hence,

Using a graphing calculator, the solution to the system is given below as


x=2,y=-3

Answer the following given the system of equations 2x - y = 7 and 3x + y = 3 1. Find-example-1
