3d/6+4= 19
move +4 to the other side
sign changes from +4 to -4
3d/6+4-4= 19-4
3d/6= 15
Mutiply both sides by 6/3 to get d by itself
3d/6*6/3- Cross out 3 and 3 , divide by 3 and becomes 1
Cross out 6 and 6, divide by 6 and becomes 1
1*1*d= d
15(6/3)- Cross out 15 and 3, divide by 3
15/3= 5
3/3= 1
5/1= 5 , 5*6= 30
answer: d= 30
