Algebraic Justification in Resource Modeling

A facility manager is using the equation (y+9)=8-(y + 9) = 8 to determine the required adjustment for a building's ventilation system. After distributing the negative sign to reach the simplified form y9=8-y - 9 = 8, the manager adds 99 to both sides of the equation to isolate the variable term. What is the formal name of the algebraic property that justifies adding the same value to both sides of an equation to maintain its equality?
