3x-18 = 9
Adding 18 on both the sides we get,
3x = 27
Dividing both sides by 3 we get,
x = 9.

What is x if x-3x equals 18?
If x-3x=18 then x equals -9
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
Y equals 5x plus 18 y equals 2x plus 9?
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
1 divided by 3x plus 6 equals 9?
1/3x + 6 = 9 Restating the problem x + 18 = 27 I multiplied by 3 x = 9 I subtracted 18 from 27
How do you get y by itself in the equation 3x-6y equals 9?
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
What is x if x-3x equals 18?
If x-3x=18 then x equals -9
What is 4x plus 6 minus7x plus 9 equals 18?
4x+6-7x+9=18-3x+15=18-3x=3x=-1
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
3x plus 9 equals 27?
27-9 =18. 18/3 =6
What does x equals in 3x 12 equals 18?
3x+12 = 18 3x = 18-12 3x = 6 x = 2
