The given equation can be simplified to 2x + 3y = 6 but that is about it.
Given 2 unknown variables (x and y) you need two independent equations to solve for them. The only other thing you can so with the above equation is to express
y in terms of x : y = (6 - 2x)/3 = 2 - 2x/3
or
x in terms of y: x = (6 - 3y)/2 = 3 - 3y/2
Both different (and possibly clumsier) ways of saying the same thing as the original equation.
do you mean what is 3+6+9-12? The answer is 6: 3+6=9 9+9=18 18-12=6 :)
6a + 9; a = 36a + 9= 6(3) + 9= 18 + 9= 27
Yes it is 9+9=18
27
Do you mean: 5x + 9 - 7x + 6 = x - 18 If so, you can solve this question at this manner: -2x + 15 = x - 18 3x = -3 x = -1
Equality

few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
27-9 =18. 18/3 =6
4x+6-7x+9=18-3x+15=18-3x=3x=-1
No! It equals 15, but 9-6=3.
18
It is: 18+6+6+6+6+9 = 51
9 plus 135 = 16 The series is formed by dividing the second number by the first number and then adding 1 to the quotient. 18 ÷ 3 = 6 : 6 + 1 = 7 14 ÷ 7 + 2 : 2 + 1 = 3 18 ÷ 6 = 3 : 3 + 1 = 4 112 ÷ 8 = 14 : 14 + 1 = 15 135 ÷ 9 = 15 : 15 + 1 = 16
6a + 9; a = 36a + 9= 6(3) + 9= 18 + 9= 27
(6 x 9) + 6 + 9 = 69
Yes it is 9+9=18
