Given equations are -2x -3y = 4 ---> (1)

-6x + 4y = -38 ---> (2)

To elimnate the  variables in two equations,

Must be coefficients of  one variable in two equations are same value with positive or

negitive sign.

In this case  to eliminate variable ,

Coefficient  of x  = -2 in equation (1).

Coefficient  of x  = -6 in equation (2).

± 3 should multiply the first equation to solve in elimination method.

None of the option correct choice.
