Answer:
-5x-4
Step-by-step explanation:
You first have to combine like terms. (-6x + x) + (+3 -7) = -5x-4
Answer:
-5x + 7
Step-by-step explanation:
-4x - 2y = -2
x - 2y = 9
First, you're going to subtract the equations from each other.
(-4x - 2y = -2) - (x - 2y = 9)
Next, you need to get rid of the equal sign in both equations.
(-4x - 2y = -2) - (x - 2y = 9)
+2 +2 -9 -9
After you get rid of the equal signs, you will distribute the sign to the equation and then subtract everything.
-4x - 2y + 2 - x + 2y + 9
Now, combine the like terms.
(-4x -x) + (-2y + 2y) + (2 + 9)
Finally, calculate the terms and solve.
-5x + 7

Answer:
8x; x ≤ $23.75
Step-by-step explanation:
You have to buy 8 trains with 190 dollars. You can't use more money or have more trains.
8x ≤ 190
Divide by 8 on both sides.
x ≤ $23.75 per train
