To eliminate the y-terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before ad
ding the equations together?
First Equation: 5x - 4y = 28
Second equation: 3x - 9y = 30
The first equation should be multiplied by 3 and the second equation by 5.
The first equation should be multiplied by 9 and the second equation by -4.
The first equation should be multiplied by 3 and the second equation by -5.
The first equation should be multiplied by 9 and the second equation by 5.
You can see that 24 cannot be divided by 5, but you can subtract 4 from 24 to get 20, which is a multiple of 5. 20 divided by 5 is 4, so they can make 4 teams.
