Answer:
Step-by-step explanation:
Given that,
y=x+2 equation 1
2x-y=-4 equation 2
This is a simultaneous equation.
Substitute equation 1 into equation 2
2x-y=-4. Since y=x+2
2x-(x+2) = -4
2x-x-2 = -4
x-2 = -4
x = -4+2
x = -2
Also from equation 1
y=x+2
Since x=-2
y=-2+2
y=0
Then, solution (x, y) = (-2,0)
Answer:
This depends on the price of how much the tickets cost in total so if the 10 tickets cost $10 dollars then the unit price would be $1
Step-by-step explanation:
You need to divide the total number by the number 10 and then that would be your unit price.
X+2y=12
X+2y=12-12
X+2y-12=0
2x+4.7=77.8
double the unknown number then add 4.7
