"a number" suggests that you have an unknown number. Represent it by x.
.
The sum of "a number" and 7, can therefore be represented by (x + 7). Then 3 times that is:
3(x + 7).
.
"Yields the same result as" is just a fancy way of saying "equals" ... So up to this point
you have:
.
3(x + 7) =
.
Next, twice the same number is 2x and that decreased by 4 is 2x - 4. So the total algebraic
statement becomes:
.
3(x + 7) = 2x - 4
.
