Explain step by step how to find x :   17-(6x+3)=-16

anonymous · Answer

$$17-6x-3=-16$$

anonymous · Answer

$$-(+6x+3) \rightarrow -6x-3$$

anonymous · Answer

There is an implied + sign before the initial 6x, and this (AND the 3 plus sign) turns to a '-' sign, as everything in the brackets is minused, which reverses the signs.

anonymous · Answer

$$-(-2x+4-5y+3) \rightarrow (2x-4+5y-3)$$

anonymous · Answer

$$-(a-b) \rightarrow b-a$$
