We have
7x - 2(3 + 4x) = 19
The expression 2(3 + 4x) expands to 6 + 8x by the distributive property, so the equation is equivalent to
7x - (6 + 8x) = 19
7x - 6 - 8x = 19 (don't forget to distribute the negative sign throughout)
-x - 6 = 19, I'll multiply both sides by -1 to get rid of the negative signs.
x + 6 = -19
x = -25
