Answer:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
-37/5= y
4x-3(-37/5)=31
x=11/5
Answer:
I think it's 4y

I think it's 4y is because if y = 0 they all work but 4y which is 0 while all the others are 4
Answer:Since the integers are closed under addition, . m C n C 1/ is an integer, and hence the last equation shows that x C y is even. Therefore, we Page 3 Appendix C. Answers for Exercises 539 have proven that if x and y are odd integers, then x C y is an even integer. P1 There exists an integer k m D 2k.
