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 $\\10(-7x+y) = 0.4(10) \\-70x+10y=4$.
