When exactly one of the integers is negative.
For example, -24*(36)=-864 which is smaller than any of the factors of the integers.
I think you forgot to mention Susan's current age if not:
x+5
x-4
6x
X = # of perfomances
y = total amount of money
Income: y = 7500x
Expense: y = 5900x + 88000
Substitution:
7500x = 5900x + 88000
1600x = 88000
x = 55
y = 7500(55) = $412,500
55 performances are needed to break-even.
X + 5 + 11x = 12x + y
Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)
Subtract 12x from each side makes each zero.
5 = y
So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82
x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125
x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989
So we verified y = 5
Answer:
x = - 7
Step-by-step explanation:
- 3x + 7 = 28
- 3x + 7 - 7 = 28 - 7
- 3x = 21
- 3x/3 = 21/3
- x = 7
x = - 7
