I got 88 using google??
Used this http://numberz.co.uk/ES.html
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
that was my quick working out, it could be wrong as its been a long time since i used google lol
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
