Answer: (2, -3)
The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
Step-by-step explanation:
As given the equations are .
4x+y=5
3x+y=3
Subtracted 3x+y=3 from 4x+y=5 .
Thus
4x - 3x + y - y = 5 - 3
x = 2
Put in the equation 4x+y=5 .
4 × 2 + y = 5
8 + y = 5
y = -8 + 5
y = -3
Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .
(2, -3)
If you add 21,42,50, and 205 you will get your answer

Answer:
Total number of cups in package are 2400.
Step-by-step explanation:
Given : An economy package of cups has 720 green cups.
And the green cups are 30% of the total package.
We have to find the number of total cups in the package.
Let the package contain x cups in total.
Given: green cups are 30% of the total package that is 30% of x,
Also , given package has 720 green cups.
Thus, 30% of x = 720
Solving for x, we have,
Thus, total number of cups in package are 2400.
