Q. How many solutions does the system have?{y=4x8 4y=4x8\begin{cases} y = 4x-8 \ 4y =4x-8 \end{cases}
  1. Write Equations: Write down the system of equations.\newlineWe have the following system of equations:\newline{y=4x8 4y=4x8\begin{cases} y = 4x-8 \ 4y =4x-8 \end{cases}
  2. Compare Equations: Compare the two equations.\newlineThe first equation is y=4x8y = 4x - 8.\newlineThe second equation is 4y=4x84y = 4x - 8, which can be simplified by dividing both sides by 44 to get y=x2y = x - 2.\newlineHowever, this is a mistake. We should divide the entire right side by 44, not just the xx term.
