I don’t know how to use elimination without getting decimals when I divide to get like x’s or y’s

The equation for elimination is
-4x-2y=14
-10x+7y=-25

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.
