collect like terms
2x + 6x - 10y - 18y
8x - 28y
Answer:
Step-by-step explanation:
Since it is the midpoint we can say:
12x - 1 = 8x +11
All we have do to is get all the x's alone on one side
12x - 1 = 8x + 11
12x = 8x + 12 (add both sides by 1)
4x = 12 (subtract both sides by 8x)
x = 3 (divide both sides to get what x is)
The answer is -9x
