One train will be travelling at 60 mph, and the other train will be travelling at 70 mph. 70 * 5.5 = 385, 60 * 5.5 = 330. 330 + 385 = 715
substitution
y = 7x-26 (1)
y = 4x-11 (2)
1⇒2
7x-26=4x-11
3x=15
x=5
y = 7(5)-26
y = 9
point (5,9)
If any of your x's repeat (aka 5) then it is not a function. Because in order to be a function you cannot have any of the x's repeat or an x value has more than 1 y value.
Hope this helped!<3
