Question

For each ordered pair, determine whether it is a solution to the system of equations. 5x-3y = 7 - 2x+5y=1 Is it a solution?

Answer 1

`\begin{gathered} \text{The equation is,} \\ 5x-3y=7\ldots\text{.}(1) \\ -2x+5y=1\ldots(2) \\ \text{Substitute x}=-8\text{ in the equation (1).} \\ 5*(-8)-3y=7 \\ -40-3y=7 \\ -3y=47 \\ y=-(47)/(3) \\ So,\text{ (-8,-3) is not a solution.} \end{gathered}`
`\begin{gathered} (2,1)\text{ is a solution.} \\ (-4,0)\text{ is not a solution.} \\ (5,6)\text{ is not a solution.} \end{gathered}`
