Perform the indicated subtraction.
12 - 9 = 3

4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
7x + 7 + 6x - 9 = 13x - 2
8/9 + 3/9 + 2/9 = 13/9 = 1 4/9
It is: 11p+11 simplified
a = 1/2
6x + 9 + 2x = 8x + 9
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;

It is 9/12, which you can simplify if required.
When you simplify 49 plus 37 (49+37), the result is 86.

4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
17.2 + 3.1y + 4.2y + 9 = 7.3y + 26.2
-3 + -12 = -15
