Question

The point (-2,-7) is a solution tothis system.(4x – 3y = 1317x - y = -7TrueFalse

Answer 1

`\begin{gathered} 4x-3y=13 \\ x=(13+3y)/(4) \\ 17\cdot(13+3y)/(4)-y=-7 \\ (221+47y)/(4)=-7 \\ y=-(249)/(47) \\ then\text{ y in x } \\ x=(13+3\left(-(249)/(47)\right))/(4)=-(34)/(47) \\ \text{the point are (}-(34)/(47),-(249)/(47)) \end{gathered}`

therefore is false
