660 would be the nearest ten. you round up because the final number is with 5 or greater. if the final number was 4 or less, you would round down. I hope this helped you
Remove parentheses
3m - 7m+12 = 2 m-3
collect like terms
3m-7m-12 = 2m-6
move terms
-4m - 12 = 2m-6
collect the like terms and calculate
-4m-2m = -6+12
divide both sides by -6
-6m=6
m= -1
