2x-4>0 2x-4<0
Denominator 2x-4 cannot be zero since division by zero is not defined. There are two cases.
2x>4
Consider the case when 2x-4 is positive. Move -4 to the right hand side.
x>2
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
x+1\geq -\left(2x-4\right)
The initial inequality does not change the direction when multiplied by 2x-4 for 2x-4>0.
x+1\geq -2x+4
Multiply out the right hand side.
x+2x\geq -1+4
Move the terms containing x to the left hand side and all other terms to the right hand side.
3x\geq 3
Combine like terms.
x\geq 1
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x>2
Consider condition x>2 specified above.
2x<4
Now consider the case when 2x-4 is negative. Move -4 to the right hand side.
x<2
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
x+1\leq -\left(2x-4\right)
The initial inequality changes the direction when multiplied by 2x-4 for 2x-4<0.
x+1\leq -2x+4
Multiply out the right hand side.
x+2x\leq -1+4
Move the terms containing x to the left hand side and all other terms to the right hand side.
3x\leq 3
Combine like terms.
x\leq 1
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x\in (-\infty,1]\cup (2,\infty)
The final solution is the union of the obtained solutions.
