I got 88 using google??

Simplifying
3x + 68 = 9x + 18x
Reorder the terms:
68 + 3x = 9x + 18x
Combine like terms: 9x + 18x = 27x
68 + 3x = 27x
Solving
68 + 3x = 27x
Move all terms containing x to the left, all other terms to the right.
Add '-27x' to each side of the equation.
68 + 3x + -27x = 27x + -27x
Combine like terms: 3x + -27x = -24x
68 + -24x = 27x + -27x
Combine like terms: 27x + -27x = 0
68 + -24x = 0
Add '-68' to each side of the equation.
68 + -68 + -24x = 0 + -68
Combine like terms: 68 + -68 = 0
0 + -24x = 0 + -68
-24x = 0 + -68
Combine like terms: 0 + -68 = -68
-24x = -68
Divide each side by '-24'.
x = 2.833333333
Simplifying
x = 2.833333333
Thanks guys, I'll give her these answers
lol i thought it was just x=2 as in 32+68 is the same as 92+18 therefore x is 2. thats why i didnt finish school i suppose, the above answer seems alot more convincing even although i didnt understand any of it
Yup sorry as jimbojetset says, she needs to know what X equals, I dont understand any of this stuff
the correct answer is
X = 8.3333 (.3 recurring)
X = 25/3 (as a fraction)
...yep seems to be 8.3 something..if any letter is immediately next to a number it means that those 2 values have to be multiplied...experiment with x being 1 etc until both sides of the equation are equal....thus finding the value of x
