Answer :
multiply both sides by 5 3(15k+10)=5(12k-9)
get rid of the brackets 45k+30=60k-45
take away 45k to both sides 30=15k-45
plus 45 to both sides 75=15k
divide both by 15 k=5
get rid of the brackets 45k+30=60k-45
take away 45k to both sides 30=15k-45
plus 45 to both sides 75=15k
divide both by 15 k=5
