Which statement correctly explains how Mari could find the solution to the following system of linear equations using elimination? 2 f minus 5 g is equal to negative 9 negative 7 f plus 3 g is equal to 4

Multiply the first equation by 7 to get 14f − 35g = −63, and the second equation by 2 to get −14f + 6g = 8. Adding these equations cancels the f terms because 14f + (−14f) = 0, leaving an equation with only g. So the correct statement is to multiply by 7 and 2, then add.
