Answer:
(a) 2(3/4x+7)-3[1/2x+(-5)]
(c) 2(3/4x)+2(7)+(-3)(1/2x)+(-3)(-5)
Step-by-step explanation:
Adding -5 is equivalent to subtracting 5, so ...
(1/2x -5) = (1/2x +(-5)) . . . . transformation shown in 1st rewrite
__
When the number outside parentheses is negative, that negative value multiplies each term inside parentheses:
-3(1/2x +(-5)) = (-3)(1/2x) +(-3)(-5) . . . . shown in 3rd rewrite
__
The expressions equivalent to the original are ...
(a) 2(3/4x+7)-3[1/2x+(-5)]
(c) 2(3/4x)+2(7)+(-3)(1/2x)+(-3)(-5)
