Answer: -2

Step-by-step explanation:

We know that if system of two linear equations plotted on the graph, then the intersection point of the two lines represents the solution to the system of equations.

From the given graph , we can see that the intersection point of the two lines is at point (-2,2).

Thus, the solution to the given system of equation = (-2,2)

Therefore, the x-coordinate of the solution to the system of equations is -2.

3y = -2x + 2
y = x + 4 (Substitute the y)

3(x + 4) = -2x + 2 (Distribute)
3x + 12 = -2x + 2 (Add 3 to both sides)
+3x +3x
------------------------------------------
12 = 1x + 2 (Subtract 2 from both sides)
-2 - 2
------------------------
10 = 1x (Divide by 1 on both sides)
10/1 = 1x/1
x = 10
This is your x-coordinate

nydimaria [60]

Solution: The speed of old freight train is 0.5 miles per minute and the speed of new dart express train is 1.5 miles per minute.

Explanation:

Let the speed of old freight train is x miles per minute and the speed of new dart express train is y miles per minute.

It is given that the speed of the dart express train is three times faster than the freight train. So, it can be written as,

$3x=y$ ....(1)
