X3 the grater of 2cosecutive even integer gives the same result as - 10 from the lesser integers?

Let:

Z := set of integers,
€ := is element of,

a, b € Z, with b = a + 1 .

The "two consecutive even integers " are then described as

u = 2a, and
v = 2b = 2(a + 1).

"X3 the grater of 2cosecutive even integer gives the same result as " : I think, it's safe to assume that this part of the problem has not been deliberately encrypted,
and is supposed to mean:

(the greater of two consecutive even integers) × 3 = ...

or, referring to the considerations above

3v = 3 × 2(a + 1) = ...

respectively.

There is a minor ambiguity issue with the second part of the question, though.
" - 10 from the lesser integers": either the "-" is the minus-operator, but then this would be a rather clumsy way to express the term: u - (-10) = u + 10 = 2a + 10.

But "-" could just be meant as a separator between the two terms. Why on earth didn't you take the "=" instead? Then the whole problem would read as:

(the greater of two consecutive even integers) × 3 = (the smaller of two consecutive even integers) - 10

or,

3v = u -10 <=>

3 × 2(a + 1) = 2a -10
6a + 6 = 2a - 10
4a = -16

a = -4

u = -8, v = -6.
