Answer:
Step-by-step explanation:
Adding both equations
4x+5y+5y-4x=19+38
10y = 57
y= 5.7
Subtracting equation i from ii
5y-4x-4x-5y=38-19
-8x=9
x= -0.9
First you would divide 1.12 by 12 which is 0.093 repeating 3 times 3 to get the cost of three eggs.Therefore the answer would be he paid 28 cents for 3 eggs.
Isolate the variable by dividing each side by factors that dont contain the variable x=9
Answer: X- 4y - 12=0
step by step explanation:
First, move the constant to the left by adding its opposite to both sides
x-4y -12 = 12-12 =
X-4y-12 = 0
So the answer is X- 4y - 12=0
