A train travels 25 miles in 20 minutes. What is the train speed in miles per hour?
Answers
So,
The rate of the train is 25mi/20mins. We need (x)mi/hr. We can do that by multiplying by 3.

How do you solve substitution to solve the sytem x+y=2 -2x+y=2
Answers
so you want to make one of the equations equal to one of the placeholders exg y=x+3
so we have x+y=2 and -2x+y=2
I chose to make -2x+y=2 equal to y so -2x+y=2 add 2x to both sides y=2+2x
subsitute 2+2x for y in x+y=2 x+2+2x=2 add like terms 3x+2=2 subtract 2 from both sides 3x=0 x=0
subsitute x=0 in x+y=2 0+y=2 y=2
x=0 y=2
separate one variable in either equation, so for example:
x=-y+2 -2x+y=2
(if you dont know how to do that, tell me)
now that you have the variable separated, you can substitute the top equation in for the x in the second equation like this
-2(-y+2)+y=2
and now use the distributive property to get:
2y-4+y=2
and just combine like numbers.....
3y-4=2
and if you dont know how to solve it from here, comment to tell me but the rest of the problem would go like this:
3y-4=2 +4 +4
3y=6 /3 /3
y=2
and then you take this y and plug it back into one of the original two equations waaayy up at the top like this:
