Step-by-step explanation:
1) 2x+3y-3y=1-3y. -x+2y= -4
2x/2=1-3y/2. -(1-3y/2)=-4
x=1-3y/2. -1+3y/2= -4
x=1-3(-2)/2 3y/2= -4+1
x=1+6/2 3y/2×2/3= -3×2/3
x=7/2 y= -2
S.s{ 7/3,-2}
2). -4x-6y+6y=7-6y. 4x+y= -2
-4x/-4=7-6y/-4. 4(-7-6y/4)+y= -2
x= -7-6y/4. -7-6y+y = -2
x= -7-6/4 -5y/5= 5/5
x=-13/4 y= 1
S.s { -13/4, 1 }

Step-by-step explanation:
Answer:
120
Step-by-step explanation:
The area of the room is 300 feet^2
The carpet has a side length of 2.5 feet so you divide 300 by 2.5
300/2.5 = 120
Literally just add up the coins and their value
The correct answer is 5 1/2 because if it weren’t simplified it would be 6/2 which makes the numerator the greatest.
