Hi
Which of these equations can NOT be solved? By my maths, non of them can be...? is it a trick question?
a) 4x = 2x,
which cannot be solved for obvious reasons.
b) x + 9 = x + 8,
1 = 0
this cannot be solved as the x's negate each other.
c) 3x - 5 = 2x - 5,
3x = 2x
like a) this also cannot be solved.
d) 2x- 4 = x + 4
x = 0 (?)
this the only one that feel like has some sort of resolution..
e) 2x - 10 = 2x - 11
2x - 2x = -1
this also feels like a no.
f) 2x - 3x = 0
unless x=0 then again, cannot be solved.
SO, by my (simple) maths, non of them cannot be solved. Open for discussion. This is a question from a Swedish Exam Paper btw.
