Answer:
[tex]23 L= 23 000ml\\750ml\\50L = 50 000ml\\\\50000=x+23000+750\\x=50000-23000-750\\x=26250ml\\x=26.250L[/tex]
Step-by-step explanation:
Change all the values given to one unit. (Litres to millilitres to avoid working with decimals)
Let x represent the amount of water left to be poured.
Since all will be equal to the volume of the tank, equate all values to the total capacity of the tank.
Change the subject and solve.
Hope you understood.
Have a nice day. :)
