Question

Solve the following system of linear equations by graphing:4x + y = 4x 48-3+ + 2y = -1

Answer 1

Given:

`\begin{gathered} -(4)/(3)x+y=4\ldots\text{ (1)} \\ -(8)/(3)x+2y=-1\ldots.\text{ (2)} \end{gathered}`

Equation (1) can be written as

`y=(4)/(3)x+4\ldots\text{ (3)}`

Equation (2) can be written as

`\begin{gathered} 2y=(8)/(3)x-1 \\ y=(4)/(3)x-(1)/(2)\ldots\text{ (4)} \end{gathered}`

By equating equation(3) and equation(4)

`\begin{gathered} (4)/(3)x+4=(4)/(3)x-(1)/(2) \\ 4\\e-(1)/(2) \end{gathered}`

There is no solution.
