Question

Solve the system graphically and check x+2y the solution.x+2y=7. 2x-y= -1

Answer 1

`\begin{gathered} x+2y=7 \\ Put\text{ x=0 then y=}\frac{\text{7}}{2} \\ \text{Put y=0 then x=7} \\ 2x-y\text{ =-1} \\ put\text{ x=0 then y=1} \\ \text{put y=0 then x=}\frac{\text{-1}}{2} \\ \text{Cutting point of two graph is (}1,3\text{)} \\ \text{This is the final solution.} \end{gathered}`
