-4r + 3 and -5a + -12 and dont forget the negatives.
add r+ -6r + another r. r+ -6r= -5r+ another r = 4r and dont forget the + 3.
in the parenthasis multiply both by -4 which equals -4a + -12 -a which makes it -5a + -12.

do the parentheses and then put the like terms together
3 - 6r + r = 3 - 7r
-4(a + 3) -a = -4a-12 - a = -5a -12
