Question

Solve the system.
y = -1/3 x + 2 and x + 3y = 3

Answer 1

Plug in the first equation into the second one. Then solve for x.

Answer 2

yes, I suggest you use substitution method for fractions. It's much easier.

So you have this system: \[\left\{\begin{matrix}
\sf \color{red}{y=-\frac{1}{3}x+2} & \\
\sf \color{blue}{y + 3}\sf \color{red}{y} \sf \color{blue}{=3} &
\end{matrix}\right.\]

plug in the red requation into the blue one where the red y is.

Answer 3

sorry, the first blue \(y\) should be a \(\sf \color{blue}{x}\)

Answer 4

@gabbie96 you can use Matrices to solve this equation.

Answer 5

Why the heck would you want to use matrices tho.

Answer 6

They are parallel lines look closely
