Final answer:
The equation -7.4 + ℓ = ℓ + 9.11 has no solution.
Step-by-step explanation:
To solve the equation (-7.4) + ℓ = ℓ + 9.11, we want to isolate the variable ℓ. To do this, we can subtract ℓ from both sides of the equation: (-7.4) + ℓ - ℓ = 9.11. Simplifying the left side, we get -7.4 = 9.11. However, this is not a true statement, so there is no solution to the equation. Therefore, the correct answer is: ℓ has no solution.
