6x + 9 + 2x = 8x + 9

2x

It is 9/12, which you can simplify if required.

67

4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;

When you simplify 49 plus 37 (49+37), the result is 86.

17.2 + 3.1y + 4.2y + 9 = 7.3y + 26.2

-3 + -12 = -15

Answer: 12

You can factor it, if you consider that simpler.

11-3p

7x + 7 + 6x - 9 = 13x - 2

11p+11

It is: 2xsquared+14x-9

4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5

4p + 9 + (-7p) + 2 = 4p - 7p + 9 + 2 = -3p + 11

-9

The simple form of the equation 5 - 9 + (-1) is -5.

3x-2y+9+9y-x = 2x+7y+9

-12

x + 5 + 4 = x + 9

It is the same as 23+50 = 73

-12 + 6 - 10 - 6 +15 = -7
