Correct
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 42/7 = 6

3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
Correct
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 42/7 = 6
If -6d = 42 then 6d = -42. then divide by 6, d = -7

6m = 42 Divide both sides by 6: m = 7
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
x=42
Well, isn't that a happy little math problem! To find out what times three equals 42, we just need to divide 42 by 3. And when we do that, we get a beautiful number - 14! So, 14 times 3 equals 42. Just like painting a lovely landscape, sometimes all it takes is a little bit of math to reveal the beauty hidden within.
