Simply 5(7x-2)-14x+4

In order to simplify the expression, we will multiply everything within the parentheses by 5 and apply the -14x and +4 outside the parentheses:

5(7x-2) - 14x + 4

Expanding the parentheses by multiplying:

35x - 10 - 14x + 4

Combining like terms:

(35x - 14x) + (-10 + 4)

21x - 6

Therefore, the simplified expression is 21x - 6.
