A cuantos cm3 equivale un litro?

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
