Question

How do you solve

-3(1+6r)=14-r

Answer 1

r = (-1)

Explanation:

Firstly simplify the brackets,

; -3(1 + 6r) = -3 - 18r

then substitute on the bracket with the simplified form,

; -3 - 18r = 14 - r

then move the values with (r) to one side and the other ones without (r) to the other side

; -3 - 14 = 18r - r

; -17 = 17r

then divide both sides by 17,

; -1 = r

Hence...r = -1
