Since each month profit is $1,900, it should be multiplied by 1900 as the time goes by. For example, one month profit is 1900, two month profits are 2*1900, three months profits are 3*1900, and so on...
So, it's Y (the amount of profits after X months) = 1900*X
Answer:
x = 4
y = 3
Step-by-step explanation:
2x - 3(x - 1) = -1
2x - 3x + 3 = -1
-x + 3 = -1
- 3 - 3
(-1) -x = -4 (-1)
x = 4
y = 4 - 1
y = 3
