Question

Y = 1/4xx + 4y = 8Solve each system of equations algebraically use substitution

Answer 1

`\begin{gathered} \begin{bmatrix}y=(1)/(4)x \\ x+4y=8\end{bmatrix} \\ x+4\cdot(1)/(4)x=8 \\ x+x=8 \\ 2x=8 \\ (2x)/(2)=(8)/(2) \\ x=4 \end{gathered}`

for y

`y=(1)/(4)x=(1)/(4)(4)=1`

solution

x = 4

y = 1
