-3-6(-4k+5)=-12+3k
Solve for k: -3-6 (5-4 k) = 3 k-12 -6 (5-4 k) = 24 k-30: 24 k-30-3 = 3 k-12 Grouping like terms, 24 k-30-3 = 24 k+(-3-30): 24 k+(-3-30) = 3 k-12 -3-30 = -33: Answer: | 24 k+-33 = 3 k-12 k=1
\(-3\;\;\;\:\qquad -6(-4k+5)=-12+3k\\ -3+12\;\;\;-6(-4k+5)=-12+3k+12\\ 9\;\;\;-6(-4k+5)=+3k\\ \mbox{divide both sides by 3}\\ 3\;\;\;-2(-4k+5)=+1k\\ 3\;\;\;+8k-10=+1k\\ 8k-7=k\\ 7k=7\\ k=1\)
