step-by-step explanation:
a
(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )
= 6r + 7 + 13 + 7r
= 13r + 20
b
remove brackets and collect like terms
13 - r - 1 + r
= 12 - r
c
remove brackets and collect like terms
= - 8 - r + 2r - 4
= - 12 + r
d
remove brackets and collect like terms
= 7r - - - 6r
[- - = - - = - ]
= r -
