Best Method Using System of Equations

\[
\begin{align*}
x &= 4y + 8 \\
2x - 8y &= -3
\end{align*}
\]

X=4y+8 2x-8y=-3
lets use the substitution method 2x-8y=-3 2(4y+8)-8y=-3 8y+16-8y=-3 16 is not equal to -3 so lets try elimination
x=4y+8 2x-8y=-3
xhange the 1st equation to standard for x-4y=8 2x-8y=-3
multiply the 1st equation to remove x 2x-8y=8 2x-8y=-3 0 is not equal to 11
therefore we cannot solve using both equations so te question's answer is undefined

In this case, since one equation is in the form of x=, substitution would be best for this problem. Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.

The system of equations leads to contradictory statements using both the substitution and elimination methods, meaning there is no solution. This indicates that the equations represent parallel lines that do not intersect. Therefore, the system is inconsistent.
