You can put this solution on YOUR website!
solve 6%2F%28x%2B2%29=3%2F%28x-2%29
Cross multiply
6(x-2) = 3(x+2)
6x - 12 = 3x + 6
6x - 3x - 12 - 6
3x - 18 = 0
Graph
y = 3x -18
:
+graph%28+300%2C+200%2C+-6%2C+22%2C+-30%2C+20%2C+3x-18%29+
we can see x = 6, x intercept
:
3x - 18 = 0
3x = 18
x = 18/3
x = 6
:
Confirm this in the original problem
6%2F%286%2B2%29=3%2F%286-2%29
which is
6%2F8 = 3%2F4
