Question

If tb=5x and tu=4x-1 and ub=2x-1 what does x equal

Answer 1

If C is a point between AB then we can write AC + CB = AB

Same way we can write tu + ub = tb
tu = 4x - 1 , ub = 2x - 1 and tb = 5x
So we can write it as

$4x - 1+ 2x - 1 = 5x$

$6x - 2 = 5x$

$6x - 5x = 2$

$x = 2$

So x is  = 2.
