Answer:
Step-by-step explanation:
If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...
x(x +2) = 63
__
The equation can be rewritten as ...
(x +1)² = 64
x = -1 ±√64 = -1 ±8
The positive solution is x=7, so the positive set of integers is {7, 9}.
The negative solution is x=-9, so the negative set of integers is {-9, -7}.
Answer:
x=41
Step-by-step explanation:
2(x+3) = 88
(distribute the 2)
2x+6 = 88
- 6 - 6
2x = 82
div by 2 on both sides
x = 41
