-3m + 8 - 7 = -3m + 1
If 3m - 7 = 8, then m = 5
If: 7+3m = -29 then the value of m is -12
2(3m plus 7) using the distributave property 6m+14. maybe
3m + 11n = 3
3m + 7 = 5 Subtract 7 from both sides: 3m = -2 Divide both sides by 3: m = -2/3
m = -12
5m+2n, n-3m, 7-3n (5m+2n)+(n-3m)+(7-3n)=2m+7
17
4m + 3m = 180 7m = 180 m = 25 5/7
3m-5 = 7-21 3m = 7-21+5 3m = -9 m = -3
-3m + 8 - 7 = -3m + 1
