"like dissolves like" is an expression used by chemists to remember how some solvents work. It refers to "polar" and "nonpolar" solvents and solutes. Basic example: Water is polar. Oil is non-polar. Water will not dissolve oil. Water is polar. Salt (NaCl) is also polar. Like dissolves like, so polar dissolves polar, so water dissolves salt.
A solute dissolves in a solvent. For example, salt dissolves in water.
