23-3k+2\left(4k+6\right)=35+5k
Multiply both sides of the equation by 5.
23-3k+8k+12=35+5k
Use the distributive property to multiply 2 by 4k+6.
23+5k+12=35+5k
Combine -3k and 8k to get 5k.
35+5k=35+5k
Add 23 and 12 to get 35.
35+5k-5k=35
Subtract 5k from both sides.
35=35
Combine 5k and -5k to get 0.
\text{true}
Compare 35 and 35.
k\in \mathrm{C}
This is true for any k.
