Tackling equations that contain decimals comprises the same procedures as other algebraic equations, which primarily involves separating the variable. However, it may also necessitate additional steps to eliminate decimals. This is usually done by multiplying every term by the highest power of 10 that exists within the decimal values, effectively converting them into integers.
