Solve for substitution of Y=x-1 and 2x-y=0
2 answers:
Step One: Plug in (x-1) for y in 2x-y = 0
Step Two: Distribute the negative
<u />
Step Three: Add like terms on one side of the equation
Step Four: Subtract 1 from both sides
Step Five: Plug x into one original equation (I chose y=x-1 but you can do either one)
That's the answer to the problem, x = -1, y = -2 (-1,-2)!
Hope this helps!

I think this is the answer
Answer: $10.40
Step-by-step explanation:
The answer will be p = i/rt instead. You just flipped the process by mistake :)
van = v, bus = b, students = s
v + 6b = 372s ...eqn 1
4v + 12b = 780s ...eqn 2
divide eqn 2 by 4
v + 3b = 195s ...eqn 3
eqn 1 - eqn 3
3b = 177s
b = 59s
subst b = 59 in eqn 1
v + 354s = 372s
v = 18s
answer: each van holds 18 students and each bus holds 59 students
Answer:
$42.50
Explanation:
If you divide 34 by 4 you get 8.5. Then you just add 8.5 to 34 to get 42.50.
