8 is the answer to your question
Can you give me the problem
x+(x-2)=7 cab be used to determine the value of x.
Step-by-step explanation:
Given,
Heidi has x donations.
Grandpa Case has 2 fewer donations than Heidi.
Fewer means subtraction.
Grandpa has = x - 2
They have 7 donations in all.
Heidi's donations + Grandpa's donations = Total donations
x+(x-2)=7
x+(x-2)=7 cab be used to determine the value of x.

You're looking for values to factor this equation into (x+p)(x+q)
such that pq=12 and p+q=b
Assuming we're looking for simple values, you can start by factorizing 12:
12 = 3*4 = 2*6 = 12*1 = -3*-4 = -2*-6 = -12*-1
For 3 and 4, b would be 7
2 and 6 => b=8
12 and 1 => b=13
and for the negatives
b can be -7, -8 or -13
So the total set is -13, -8, -7, 7, 8, 13
