Answer
$7x+4y=8$
Work Step by Step
Substituting $
x=0
$ in the given equation, $
7x+4y=8
,$ results to
\begin{array}{l}\require{cancel}
7x+4y=8
\\
7(0)+4y=8
\\
4y=8
\\
y=\dfrac{8}{4}
\\
y=2
.\end{array}
Substituting $
y=0
$ in the given equation, $
7x+4y=8
,$ results to
\begin{array}{l}\require{cancel}
7x+4y=8
\\
7x+4(0)=8
\\
7x=8
\\
x=\dfrac{8}{7}
.\end{array}
Substituting $
y=-1
$ in the given equation, $
7x+4y=8
,$ results to
\begin{array}{l}\require{cancel}
7x+4y=8
\\
7x+4(-1)=8
\\
7x-4=8
\\
7x=8+4
\\
7x=12
\\
x=\dfrac{12}{7}
.\end{array}
