Answer:
The cost of large drinks are $5 and the small drinks are $3.
Explanation:
5+5+5+3+3=21
2x5=10 4x3=12 10+12=22 OR (2)5+(4)3)=22
Answer:
x = 5, y = -2.
or as an ordered pair it's (5, -2).
Step-by-step explanation:
2x + 3y = 4
y = 5x - 27
-5x + y = -27 Multiply this by - 3:
15x - 3y = 81 Add this equation to the first equation:
17x = 85
x = 5
Plug this into the second equation:
y = 5(5) - 27
y = -2.
Answer:
The value of x and y for the given two linear equation is x = 7 , y = - 3
Step-by-step explanation:
Given two linear equation as :
x + 2 y - 1 = 0
Or, x + 2 y = 1 ..........A
x - 2 y = 13 ............B
Now, Solving both equations A and B
i.e (x + 2 y) + (x - 2 y) = 1 + 13
Or, (x + x) + (2 y - 2 y) = 14
Or, 2 x + 0 = 14
Or, 2 x = 14
∴ x =
i.e x = 7
Now, Put the value of x into eq A
So, 7 + 2 y = 1
Or, 2 y = 1 - 7
Or, 2 y = - 6
∴ y =
i.e y = - 3
So, The value s of x = 7 and y = - 3
Hence, The value of x and y for the given two linear equation is x = 7 , y = - 3 Answer
