$6 + 8 x$ $6+8x$

Consider $- (- 3 x)$ $-(-3x)$

This is the same as: $(- 1) \times (- 1) \times (3 x)$ $" " (-1)xx(-1)xx(3x)$

But $(- 1) \times (- 1) = + 1$ $" "(-1)xx(-1) = +1$ giving

$(+ 1) \times (3 x) = + 3 x$ $(+1)xx(3x)=+3x$

Given: $6 + 5 x - (- 3 x)$ $" "6+5x-(-3x)$

Write as: $6 + 5 x + 3 x$ $" "6+5x+3x$

$= 6 + 8 x$ $= 6+8x$
