4m+9+5m-12=42 9m=45 m=5
m + 9 = 2 Therefore, m = 2 - 9 m = -7
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.
If: 9m=108 m=12 (I divided each side by 9 to isolate 'm').
m = 31m + 9 = 1(3) + 9 = 3 + 9 = 12
4m+9+5m-12=42 9m=45 m=5
-4M+3=-9 -4M=-12 M=-12/-4 Negatives Cancel M=12/4 M=3
3 + 6 + m + 12 + 5 = 30 9 + m + 17 = 30 m + 26 = 30 m = 30 - 26 = 4
m = 5
-12=m+4 -16=m
m + 9 = 2 Therefore, m = 2 - 9 m = -7
1.92 m
the answer to that is 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;
22m Think of the "m" as a "monkey". 2 monkeys + 2 monkeys + 9 monkeys + 9 monkeys = 22 monkeys
m = -12
