Let the smaller integer be x.
The larger integer is x + 1.
x(x + 1) = 420
x^2 + x = 420
x^2 + x - 420 = 0
The constant is -420.
-6x + 100 = -10x + 160
+ 10x + 10x
4x + 100 = 160
- 100 - 100
4x = 60
4 4
x = 15
Answer:
3/7 + 3/7 = 6/7
Step-by-step explanation:
The first rule of adding fractions is that never add the denominators, only the numerators. But this is only in the case that the denominators are the same(in this case, 7).
We only add the numerators:
3 3 6
-- + -- = --
7 7 7
Notice that all the denominators are the same. The answer that is simplifies would be 6/7.

Answer:
Infinite/many
Step-by-step explanation:
3x + 7 + 2x = 5x + 7
3x + 2x + 7 = 5x + 7
5x + 7 = 5x + 7
5x - 5x + 7 = 7
7 = 7
