Answer:
a is 3x-3+1=3x-2 B is -1-y+3+y=2 C is -x+x+2 = 2
Step-by-step explanation:
a has 3 positive x's and 3 negative ones and 1 so the equation is 3x-3+1 and to simplify you would do -3+1 which is 2 and 3x is simplified enough so a is 3x-3+1=3x-2
B one negative 1 and 1 negative y 3 positive ones any one positive y. so the equation is -1-y+3+y and the answer is 2 everything elese cancels out.
C one negative x one positive x and 2 positive ones so the equation is -x+x+2 and when you simplify you get just 2 again.
