Answer:
Step-by-step explanation:
The given system of equations is 4x - 9y = 7 and -2x + 3y = 4
In this system of equations in order to eliminate the x- terms we will multiply by a number so that coefficients of x may become same.
Therefore, to eliminate the x - terms we multiply second equation by 2.
Similarly to eliminate the y-terms we will multiply the equation by a number so that coefficient of y in both the equations become same.
Therefore, we will multiply second equation by 3.
