So... let's say, we have two numbers "a" and "b",
"a" is the smaller one, "b" is the larger one
so, their sum is 6
a + b = 6
3 times the smaller => 3 * a or 3a
now, two less than that
3a - 2
that equals the larger "b"
3a - 2 = b
solve for "a",
now, what's "b"? well, 3a - 2 = b :)
"a" is the smaller one, "b" is the larger one
so, their sum is 6
a + b = 6
3 times the smaller => 3 * a or 3a
now, two less than that
3a - 2
that equals the larger "b"
3a - 2 = b
solve for "a",
now, what's "b"? well, 3a - 2 = b :)
