Are (2x+4)/(3x+6) and 2/3 equivalent expressions? Please explain why or why not.

Question

texaschic101 · Answer

(2x + 4)/(3x + 6) = 2/3 (cross multiply)
(3)(2x+ 4) = (2)(3x + 6)
6x + 12 = 6x + 12
They are equivalent expressions because they equal each other.

By the way, the x has infinite solutions....it can be anything, and it will still equal.

Another way to solve is:

$$(2x + 4 ) = 2 ( x+2)$$
$$(3x + 6) = 3(x + 2)$$
Now $$\frac{ 2 (x + 2) }{ 3 (x + 2) } = \frac{ 2 }{3 }$$
Since (x+2) cancels out in both numerator and denominator
