2(2x−5)−2x+4=−18

Sure, let's solve the equation step by step:

1. Distribute the 2 in the first term: 22x - 25 - 2x + 4 = -18
2. Simplify: 4x - 10 - 2x + 4 = -18
3. Combine like terms: 2x - 6 = -18
4. Add 6 to both sides: 2x = -12
5. Divide both sides by 2: x = -6

So, the solution to the equation 2(2x−5)−2x+4=−18 is x = -6.
