Just substitute any number for one variable to find the value of the other.
Eg:
2x-y=11
2(1)-y=11
2-y=11
-2 -2
-y=9
-y/-1=9/-1
y=-9
So (1,-9) is a solution to the equation.
Follow the steps and find many more solutions.
Hope I help you.
Answer:
B and D
Step-by-step explanation:
slope = 2/7

Answer:
4 ounces
Step-by-step explanation:

Hence, 4 ounces of oil will be used for the soup.
B- n/ 3 - 8 = 18....................
A= -48
b= -240
c= 8
D-F I have no clue yet what that is
