factor by grouping 7m(m-2)+6n(2-m)
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
6n + 17 = 5 subtract 17 from both sides 6n = -12 divide both sides by 6 n = -2 (negative 2)
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
If you mean -5(6n+6) = 30 then -30n -30 = 30 and so n = -2 when evaluated
6n = 12 n = 2
factor by grouping 7m(m-2)+6n(2-m)
3n+2+3n+2=6n+4
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
7n3 + 6n = n*(7n2 + 6)
6n + 5n is 11n.
It is the same as: 30n^2 +36n
6n + 17 = 5 subtract 17 from both sides 6n = -12 divide both sides by 6 n = -2 (negative 2)
5mn + 6n - 14
6(n + 2) = 6n + 12
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
