X equals 9.
3x+9/2=9 3x=9-9/2 3x=9/2 x=9/6 x=3/2
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
2x + 6 = -9 + 5x Subtract 2x from both sides: 6 = -9 + 3x Add 9 to both sides: 15 = 3x Divide both sides by 3: 5 = x
3x-y = 9 2x+y = 6 Add both equations together: 5x = 15 x = 3 and y = 0
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
4x+6-7x+9=18-3x+15=18-3x=3x=-1
X equals 9.
The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
27-9 =18. 18/3 =6
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
3x+9/2=9 3x=9-9/2 3x=9/2 x=9/6 x=3/2
3x+24+2 = 53 3x = 53 -26 3x = 27 x = 9
the answer is -3x = 0
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x-3 = 6 3x = 6+3 3x = 9 x = 3
2x + 6 = -9 + 5x Subtract 2x from both sides: 6 = -9 + 3x Add 9 to both sides: 15 = 3x Divide both sides by 3: 5 = x
