Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.

Answer:
x₁ = 2
x₂ = 10
Step-by-step explanation:
x² + 20 = 12x
x² - 12x + 20 = 0
(x-2)(x-10) = 0
then:
x₁ = 2
x₂ = 10
Check:
x₁
2² + 20 = 12*2
3 + 20 = 24
x₂
10² + 20 = 12*10
100 + 20 = 120
