4k-32-3\left(5-4k\right)=6\times 3k-7
Use the distributive property to multiply 4 by k-8.
4k-32-15+12k=6\times 3k-7
Use the distributive property to multiply -3 by 5-4k.
4k-47+12k=6\times 3k-7
Subtract 15 from -32 to get -47.
16k-47=6\times 3k-7
Combine 4k and 12k to get 16k.
16k-47=18k-7
Multiply 6 and 3 to get 18.
16k-47-18k=-7
Subtract 18k from both sides.
-2k-47=-7
Combine 16k and -18k to get -2k.
-2k=-7+47
Add 47 to both sides.
-2k=40
Add -7 and 47 to get 40.
k=\frac{40}{-2}
Divide both sides by -2.
k=-20
Divide 40 by -2 to get -20.
