4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
The answer to 7 x 6 plus 9 is 51. You have to multiply 7 by 6 which equals 42 and add 9 onto it which equals 51.
42
7x + 9 = 51 7x = 42 x = 42/7 = 6
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;
42/9=4.666666666666667
7+2+5= 14 35 42
That only works for people who are eleven.
-2x = 12 so x = -6 giving -30 + 9 = -42 + 21. Both sides = -21.
67+8+9+42 = 126
