Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
