Answer:
X = -2
Step-by-step explanation:
Vertical lines go up and down. That means the x value is constant and the y value changes. We have an x value of -2
X = -2
X + 4 = 19 -2x
3x = 15
x=5
5 is the number
The answer is 35.
50%, another way of saying half, of 70 is 35.
5x + 8000 = 3x + 10000
x = 1000
