Answer

$2x+7y=28$

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 get $\\\frac{2}{7}x+y=4$. To make all the coefficients integers, multiply both sides by 7: $\\7(\frac{2}{7}x+y)=4(7) \\2x+7y=28$.
