Answer 1

let's do some... i dunno what it call :l just solve it shall we?
3k-1=7k+2
okay :v let's switch those number~~
3k-3k-1=7k-3k+2 ( you know how it take off right?)
-1=4k+2
-1+1=4k+1+2
0=4k+3
0+(-3)=4k+3-3
-3=4k
k= -3 over 4~~~

there is the shorter way but depend on you \m/
3k-1=7k+2
3k-3k-1=7k-3k+2
-1=4k+2
-1-2=4k+2-2
-3=4k
k= -3 over 4~~~

there you go :3 good luck
