Which constants can each equation be multiplied by so that one variable is eliminated when the equations are added? Check all that apply. The first equation can be multiplied by 5 and the second equation by –6 to eliminate the y. The first equation can be multiplied by –5 and the second equation by 6 to eliminate the y. The first equation can be multiplied by –5 and the second equation by 7 to eliminate the x. The first equation can be multiplied by 5 and the second equation by –7 to eliminate the x. The first equation can be multiplied by –5 and the second equation by 10 to eliminate the x.
7 x + 12 y = 54. 5 x + 10 y = 60.
