two trains leave stations 588 miles apart at the same time and travel toward each other. One train travels at 95 mph while the other travels at 115 mph. how long will it take for the two trains to meet? Do not do any rounding.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: answer is b.

[m < b = 120º]
