Question

Please help me finish this problem it’s giving me trouble

Answer 1

Given

`\begin{gathered} y=(7)/(5)x-(3)/(5)....Equation\text{ i} \\ \\ 7x-5y=8...Equation\text{ ii} \end{gathered}`

Solution

multiply all through by 5 equation

We have

`5y=7x-3\text{ ...equation iii}`
`\begin{gathered} Rearrange\text{ equation iii} \\ -7x+5y=-3 \\ \end{gathered}`

We have

`\begin{gathered} -7x+5y=-3...Equation\text{ iii} \\ \end{gathered}`

Add equation ii and Equation iii

`\begin{gathered} 7x-5y=8\text{ ....Equation ii} \\ -7x+5y=-3\text{ ....Equation iii} \end{gathered}`

We now have

`0=5`

This means NO SOLUTION
