It appears there might be a typographical error in your expression. The equation "x + x - 20 = x + 5" can be solved. Let's go through the steps:
Combine like terms on the left side: \[ 2x - 20 = x + 5 \]
To isolate the variable \(x\), subtract \(x\) from both sides: \[ 2x - x - 20 = 5 \] This simplifies to: \[ x - 20 = 5 \]
Now, add 20 to both sides: \[ x = 25 \]
So, the solution is: \[ x = 25 \]
