Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:
750.5
Step-by-step explanation:
Step by step:
3 x 9/10
Turn 3 into a fraction
3/1 x 9/10
Now multiply straight across
3x9=27 and 1x10=10
So you get
27/10 or 27/10 or 2.7
This can also be completed by simply turning 9/10 into a decimal and doing
3 x 0.9 = 2.7
Answer:
Front section tickets: $40
Back section tickets: $25
Step-by-step explanation:
If x is the price of back section tickets, and x + 15 is the price of front section tickets, then:
275 (x + 15) + 325 x = 19125
275 x + 4125 + 325 x = 19125
600 x = 15000
x = 25
So back section tickets are $25, meaning front section tickets are $40.
