Solve for m 0.6m +3=2m+0.2
DaniilM [7]
So in equations you want to do the same thing to both sides so that the equation will stay equal

when dealing with one unknown number (m) try to get them all on the same side

0.6m+3=2m+0.2
I usually like positive unknowns so
subtract 0.6m from both sides
3=1.4m+0.2
subtract 0.2 from both sides
2.8=1.4m
divide both sides by 1.4
2.8/1.4=2=x

if dividing by decimals move the decimal either round the decimals up or down then divide. or multiply them by the 10 to the same power then divide.

x=2
