Answer:
Step-by-step explanation:
for 1 batch of pancake = 2 2/3 = 8/3 cups
for 2 1/2 = 5/2 pancake = 8/3 * 5/2 = 40/6 cups = 6 4/6 cups
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
My guess would be -54 because we are starting with -54
