Step-by-step explanation:
Answer:
(3,-1)
Step-by-step explanation:
So we have the system of equations:

As directed, add straight down. The y-variable will cancel:

Now, divide both sides by 5. The left cancels:

So x is 3.
Now, substitute 3 for x in either of the equations:

Substitute 3 for x:

Multiply:

Subtract 9 from both sides:

So, our answer is: x=3, y=-1 or (3,-1).
And we are done :)
It cost $5 for his brother's ticket.
Step-by-step explanation:
Let,
Micheal's ticket price= x
His brother ticket price = y
According to given statement;
x+y=12 Eqn 1
y = x-2 Eqn 2
Putting value of y from Eqn 2 in Eqn 1

Dividing both sides by 2;

Putting x=7 in Eqn 2

It cost $5 for his brother's ticket.
