Answer:
y = 3x+7/2, and x = (2y-7)/6
Step-by-step explanation:
We can set up 2 equations given the information.
Let the price of advance ticket be represented by A and same day ticket by S
A + S = 50
20A + 40S = 1700
Solve for A in the first equation by subtracting S on both sides.
U will get A = 50 - S
Now substitute 50 - S for A in the second equation.
20 (50 - S) + 40S = 1700
1000 - 20S + 40S = 1700
20S = 700
S = 35
Same day ticket costs $35 and advance ticket costs $15
Is it 3b-2a=5a-6
or
3b+2a=5a-6
you are missing the sign of 2a
