Answer:
Sitting fee - 32$
Step-by-step explanation:
This is a system of equations(let x represent the sitting fee)
x+6y=50
x+11y=65
You want to isolate the x variable - x+6y-6y=50-6y ; x = 50-6y
Input this into the 2nd equation: 50-6y+11y=65 ; 50+5y=65
Subtract 50 from both sides. 5y=15 (Divided 5y on both sides) ; y=3
Now that y = 3 input this into any equation I choose the 1st one.
x+6(3) = 50 ; x + 18 = 50 (Subtract 18 on both sides to get x)
x = 32
Prove: 32 + 6(3) = 50 ; 32+18 = 50 ; 50 = 50 True

Step-by-step explanation:
find area of the big triangle then split the remaining shape into a large rectangle and a smaller rectangle
Answer:
2x+y=5;14x-7y=35
{x,y} = {5/2,0}
System of Linear Equations entered :
[1] 2x + y = 5
[2] 14x - 7y = 35
Steps:
// Solve equation [1] for the variable y
[1] y = -2x + 5
// Plug this in for variable y in equation [2]
[2] 14x - 7•(-2x+5) = 35
[2] 28x = 70
// Solve equation [2] for the variable x
[2] 28x = 70
[2] x = 5/2
// By now we know this much :
x = 5/2
y = -2x+5
// Use the x value to solve for y
y = -2(5/2)+5 = 0
Solution :
{x,y} = {5/2,0}
