4m+9+5m-12=42 9m=45 m=5
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
20
M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.
4m + 12 = 604m + 12 -12 = 60 -12 (1st subtract 12 from both sides)4m = 484m/4 = 48/4 (now divide both sides by 4 to solve for m)m = 12
4m+9+5m-12=42 9m=45 m=5
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
6m + 5n - 4m + 7n = 2m + 12n
4m+15=8m-5 or,4m=20 or,m=5
It is [4m-1, (4m-2)/3]
simplified it equals, 9m+8
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
4m-5 equals = -1
4m + 3m = 180 7m = 180 m = 25 5/7
-4M+3=-9 -4M=-12 M=-12/-4 Negatives Cancel M=12/4 M=3
