Match each system of equations with the constant that can be multiplied by equation A to create a system of equations that can be solved using the linear combination method. Equation A: 3x - 2y = 5
Equation B: 9x + 7y = -34

Equation A: 3x – 4y = 5
Equation B: 7x + 8y = 4

Equation A: 13x - y = 51
Equation B: 12x + 3y = -90

OPTIONS: 3, -3, 2

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

look at photo

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

umm im not really sure because i never had to do this
