Question

Graph these equations:5x–4y=20x=4

Answer 1

We will first solve by substituting the value of x and then plot to emphasise our answer.

`\begin{gathered} 5x-4y=20 \\ x=4 \\ \text{ Substituting this value of x gives:} \\ 5(4)-4y=20 \\ y=(20-20)/(-4)=0 \end{gathered}`

We have our graph below:
