Question

Graph and check to solve the linear equations 2x-3y = 9 x=-3

Answer 1

Graph the linear equations.

The intersection point is (-3,-5).

Subtitute -3 for x and -5 for y in equation 2x-3y=9 to check the solution.

`\begin{gathered} 2\cdot(-3)-3\cdot(-5)=9 \\ -6+15=9 \\ 9=9 \end{gathered}`

The point (-3,5) satify the equation 2x-3y=9. The point (-3,-5) also lie on the line x=-3.

So point (-3,-5) is the solution of system of linear equation.
