Assuming you mean:log9x + log9(x-2) = 12
First, I would use the basic laws of logarithms, to combine the two terms on the left.
Then you can take antilogs base 9 on both sides.
How do you solve 4y plus x equals 8
Not enough information to solve
If: a = b+c+d Then: c = a-b-d
You cannot solve x plus y since that is an expression, not an equation (nor inequality).
Simplified its 12r+3s
There's nothing to solve, it's simply an expression.
There is no rational factorisation to this expression.
a= -0.8
You need to solve x before I can answer this
you add the together and get 46
When simplified it is: 1-8x
