2(k-3)+21=-3
We move all terms to the left:
2(k-3)+21-(-3)=0
We add all the numbers together, and all the variables
2(k-3)+24=0
We multiply parentheses
2k-6+24=0
We add all the numbers together, and all the variables
2k+18=0
We move all terms containing k to the left, all other terms to the right
2k=-18
k=-18/2
k=-9
Hope this helped :)
