Ok,
The total is 63$:
= 63
It shows us one of the numbers for the equation, 13
+ 13 = 63
Two passes together plus the thirteen equals the total of 63$
the price of the pass is unknown, so we can use a variable to figure it out:
2x + 13 = 63
Now we solve
First subtract 13 from both sides:
2x + 13 - 13 = 63 - 13
Then divide both sides by 2:
2x ÷ 2 = 50 ÷ 2
Now we get our answer:
x = 25
Answer:
(-3,-2)
Step-by-step explanation:
y = -x - 5
y = 2x + 4
plug in one of the y equations
(2x+4)= -x - 5
2x+4=-x-5
3x=-9
x= -3
plug in x to one of the y equations
y= -(-3) -5
y=3-5
y= -2
x= -3, y= -2
