Answer

$30x+10y=-25$

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: $\\3x+y=-2.5$. To make all the coefficients integers, multiply both sides by 10: $\\10(3x+y) = -2.5(10) \\30x+10y=-25$.
