Answer
$-70x+10y=4$
Work Step by Step
RECALL:
The standard form of a linear equation is
$Ax + By = C$,
where
A, B, and C are real numbers and A and B are not both zero.
Write the given equation in standard form to have
$\\-7x+y=0.4$.
To make all the coefficients integers, multiply both sides by 10 to get
$\\10(-7x+y) = 0.4(10)
\\-70x+10y=4$.
