Make sure that whatever you do to one side you also do to the other. It's also important to remember the distributive property: a(b + c) = a b + a c. Also, the aim here is to isolate n.
-3*(1 - 2n) = 63 -3(1) - (-3)(2n) = 63 | Distributed the -3 through the parentheses -3 + 6n = 63 -3 + 6n + 3 = 63 + 3 | Added 3 to both sides 6n = 66 6n /6 = 66 /6 | Divided both sides by 6 n = 11
Hope this helps! :)
To solve for n in the equation 63 = − 3 ( 1 − 2 n ) , we distribute and isolate n . After simplifying, we find that n = 11 .
